Abbreviations Explained for Non-Latinists

Methods of referring to parts of the Summa theologiae

Miscellaneous abbreviations for parts of works

A few common abbreviations for some of Thomas’ works

Methods of referring to parts of the Summa theologiae

The Summa falls into three parts, of which Thomas subdivides the second into the first part of the second part (in Latin, prima [pars] secundae [partis]) and the second part of the second part (in Latin, secunda secundae). Because Thomas never finished the third part, his followers cut and pasted an ending from his earlier writings; their work is “the supplement.” You will see the following in notes and parenthetical references:

These parts break down into questions (qq.); and each question (in Latin, quaestio, abbreviated q. or quaest.) is comprised of articles (etymologically, “little joints” in the organic whole; a. = article). Most articles contain “objections” (suggested arguments) on one side of an issue, an argument or quotation supporting the other side and introduced with the formula sed contra (“on the other hand”), Thomas’ solution (solutio) in the body (corpus) of the article, and replies to the objections; replies open with the Latin preposition ad (“to” or “toward”) followed by an ordinal number (e.g., “ad primum” means “in reply to the first objection,” while “ad tertium” indicates the reply to the third). Here are sample citations:

Instead of “ad 3,” you may see “ad 3^um” or “ad 3^m”; the -um or -m represent the Latin declensional ending, as in “ad tertium.”

Miscellaneous abbreviations for parts of works

c. = caput, “chapter”

d. = distinction (a division within commentaries on the Sentences of Peter Lombard, the theological textbook in Thomas’ day)

div. text. = division of the text (Thomas’ outline of the text he’s commenting on)

expos. text. = exposition of the text (Thomas’ detailed interpretation)

lect. = lectio, “lesson” (units of text Thomas comments on; lessons of Aristotle’s works are usually shorter than the chapters modern readers know)

princ. = principium, “beginning”

q.^a = quaestiuncula, “little question,” an inquiry attached to an article within a question within a distinction

A few common abbreviations for some of Thomas’ works

You may see the following abbreviations, and many variations on them, in footnotes and in lists of parallel passages. Note well: Even the full titles of Thomas’ works may vary from manuscript to manuscript and, therefore, from edition to edition.

Latin Texts & Aids

For those who can read Latin

For those who wish they could read Latin

For those who can read Latin

Besides the English translations with facing Latin texts, noted above, the web offers an increasing number of Latin e-texts. Building on Roberto Busa’s work for the Index Thomisticus, Enrique Alarcón has put the writings of Thomas (and some by his contemporaries) as well as many tools for their study on-line and in a most pleasing format at www.corpusthomisticum.org. But given the vagaries of servers and browsers, it’s good to know other addresses besides, and each of the following has its advantages:

• Robert Pasnau (spot.colorado.edu/~pasnau/latinus) provides texts, links, and information about acquiring Busa’s CD-ROM.
• Joseph Magee lists many sites, especially for De ente et essentia, at www.aquinasonline.com/Texts.
• Esteban Trento offers links to e-texts of Aquinas in English, French, Spanish, Portuguese, Russian, and the original Latin at www.geocities.com/tomistas/links4.htm.
• www.intratext.com/X/LAT0012.htm presents the Postilla super Psalmos with word lists, concordances, and statistics (see www.intratext.com/Aiuto/ENG for an explanation of these tools).

For those who wish they could read Latin

Thomas kept his Latin simple and straightforward, wanting nothing to come between his readers and truth. Consequently, learning enough Latin to consult his works in the original takes far less time and effort than learning to read Cicero or Livy or Vergil. You can do it, and on-line resources can help.

Dictionaries

Grammars

Other resources

Dictionaries

The Perseus Digital Library at Tufts University provides many tools for students of classical Latin, among other things:

• A good starting place is Lewis’s An Elementary Latin Dictionary.
• For more detail, use Lewis & Short’s A Latin Dictionary, either browsing through it or looking up a particular word.
• Perseus can show you idioms in context.
• Have declensions and conjugations so confused you that you don’t even know where to look in the dictionary? Perseus will take the term which perplexes you and tell you which words it could be a form of. (For general advice on using dictionaries in a way that promotes rather than impedes learning, consult “Tips on Dictionary Work”.)
• Perseus lets you go from English to Latin as well as from Latin to English.

“Reports of my death have been greatly exaggerated,” said Mark Twain, and we might say something similar about Latin. Like a living thing (if only of the slow-moving sort), Latin changed during the Middle Ages, and even today it acquires new words. When you read medieval or later authors, you will find that, sooner or later, dictionaries of classical Latin let you down, and you will want resources which take post-classical developments into account:

• Roy J. Deferrari’s A Latin-English Dictionary of St. Thomas Aquinas (Boston: St. Paul Editions, 1960) is not on-line but deserves mention anyway as the most useful dictionary for beginners in Aquinas’s Latin. It is a portable adaptation of Deferrari’s multi-volume A Lexicon of St. Thomas Aquinas, the difference being that the Lexicon reproduces texts illustrating the various meanings of words, while the Dictionary just lists the possible meanings. Both are based principally on the Summa theologiae. Preserving Christian Publications has a 2004 reprint of the Lexicon; for availability of the Dictionary, see isbn.nu/0819844438/price.
• Not specifically about Thomas’ usage but easy to use and still in print is Leo F. Stelten’s Dictionary of Ecclesiastical Latin (Peabody, Mass.: Hendrickson, 1995).
• William Whitaker’s downloadable dictionary (users.erols.com/whitaker/words.htm or ablemedia.com/ctcweb/showcase/whitakerwords.html), like the Perseus site mentioned above, allows you to search by the word as you see it, even if you don’t know the form under which its dictionary entry would appear. The program works for DOS, Windows, or Linux, and Mr. Whitaker links to two possibilities for users of Macintosh. Those who cannot or would rather not download the program can use it by way of the web. Alex Pruss has made a version for Palm handhelds.
• There’s a handy list of “The Hard Little Words: Prepositions, Adverbs, Conjunctions (With Some Definitions of Medieval Usage)” at www.wordgumbo.com/ie/rom/lat/hardlat.txt.
• Lynn Nelson’s Latin Word List has many addresses and at least three versions, and since other sites may link to any one of them, it may prove useful to sort them out here.
  1. The most recent appears to be the 8,000-entry list at humanum.arts.cuhk.edu.hk/Lexis/Latin.
  2. An older, 5,000-entry list seems to underlie the searchable list at www.nd.edu:80/~archives/latgramm.htm (and www.nd.edu/~archives/latgramm.html), a site still worth knowing about because of its many other features.
  3. Unfortunately, the Java and HTML presentations at sunsite.ubc.ca/LatinDictionary, sunsite.ubc.ca/LatinDictionary/HyperText, and www.math.ubc.ca/~cass/frivs/frivolities.html seem based on the oldest, 3,469-entry list at langs.eserver.org/latin-terms.txt.
• If you develop an interest in medieval Latin beyond what you need for reading Aquinas, see the guides to printed and on-line dictionaries at www.grexlat.com/nexus/cone.html (click on “Thesauri”), www.ext.upmc.fr/urfist/menestrel/medlatin.htm, members.aol.com/lieberk/h_dic.htm, www-sul.stanford.edu/depts/ssrg/medieval/latdic.html, www.ucc.ie/acad/classics/CNLS (click on “resources”), www.italatin.com/lingualatina.html and bcs.fltr.ucl.ac.be/DicLanALat.html; they will lead you to Latin-Latin dictionaries, dictionaries of Latin place-names, explanations of ecclesiastical abbreviations, and many other remarkable tools.

Grammars

• For a clear and wonderfully concise grammar of classical Latin, see Charles E. Bennett’s New Latin Grammar.
• For answers to more grammatical questions than Aquinas’s style could ever occasion, see Allen & Greenough’s Latin Grammar.
• When Allen & Greenough’s classic is too much, try Anne Mahoney’s Overview of Latin Syntax.
• www.languages.uncc.edu/classics/latin/glossary.htm defines grammatical terms, a necessary service as instruction in English has changed.
• The grammar links at www.aboutlatinlanguage.com reflect the extensive teaching experience of Janet Burns; besides very clear explanations, she offers many on-line quizzes.
• diogenes.baylor.edu/WWWproviders/thorburn/latinqnahypertext.html contains a clearly organized set of questions and answers about basic Latin grammar.
• Mathematician Eric Conrad made useful notes on Latin grammar while preparing to translate nineteenth-century mathematical texts.
• If you need just a little something to jog your memory, try Lynn Nelson’s reference list of Latin grammar (langs.eserver.org/latin-grammar.txt or, for an HTML version, www.nd.edu:80/~archives/latgramm.htm and www.nd.edu/~archives/latgramm.html).
• Not on-line but still in print and noteworthy for present purposes is John F. Collins’ A Primer of Ecclesiastical Latin (Washington, D.C.: The Catholic University of America Press, 1985), which does not presuppose knowledge of classical Latin.

Other resources

• William Harris’s site contains a wealth of essays about how to approach the study of Latin, as well as Latin texts with commentary.
• Claude Pavur’s collection of “Latin Teaching Materials at Saint Louis University,” goes especially well with Wheelock’s Latin; notice also the “Reading Acceleration Machine” freeware.
• www.classics.uiuc.edu/Latin/sentence.htm shows you how to work through difficult sentences systematically.
• www.cnr.edu/home/bmcmanus/diagraminglatin.html explains how to diagram sentences.
• See www.uky.edu/AS/Classics/rhetoric.html for “A Glossary of Rhetorical Terms with Examples.”
• When learning any language, practice reading with biblical and liturgical texts, because their familiarity allows you to pick up speed.
  • You can find Jerome’s Vulgate at sacredbible.org, www.unboundbible.org and The Bible Gateway. Note also vulsearch.sourceforge.net/gettext.html, where you can download the Vulgate as HTML, PDF or plain text; for users of Windows, the site offers a free program for viewing the text side-by-side with the Douay-Rheims and for searching, bookmarking and annotating it.
  • The Vulgate has been revised in light of advances in biblical scholarship.
  • For the Latin text of the Mass (Novus Ordo), visit www.latinliturgy.com/nomass.html.
  • For a Book of Hours from 1599, see www.medievalist.net/hourstxt/home.htm.
• Haunting vocal music helps fix the patterns of a language in one’s memory. Try discs of Gregorian chant with both English and Latin in the liner notes. A personal favorite among more recent compositions is Igor Stravinsky’s opera-oratorio, Oedipus Rex; the Philips recording (438 865–2) features singers with especially clear enunciation and a booklet with parallel Latin and English.
• Anthologies and readers often include valuable introductions and notes. An especially good one for philosophers and theologians is The Confessions of St. Augustine: Books I–IX (Selections), with introduction, notes, and vocabulary by James Marshall Campbell and Martin R. P. McGuire (Englewood Cliffs, N.J.: Prentice-Hall, 1931, but still in print thanks to Bolchazy-Carducci, whose catalog every Latinist will want to peruse).
• Anyone considering advanced study of medieval Latin should consult Medieval Latin: An Introduction and Bibliographical Guide, ed. F. A. C. Mantello and A. G. Rigg (Washington, D.C.: The Catholic University of America Press, 1996); its essays survey developments in grammar, vocabulary, spelling, pronunciation, style, and literature in areas from philosophy to textiles.
