    For the sake of illustration, let us begin with a simple noun concept, like forma, “shape.” The base of this 1st declension noun, as we learned in Chapter 2 (§10, Table 2.1), is form-. Let us assume, then, that you want to express the action concept “to give something a shape,” “to shape.” In Latin, this idea can be easily conveyed by inventing a 1st conjugation verb—form-are, form-atus. It’s as simple as that. Now, if you want to express the notion “to shape again,” add a common prefix so as to get re-form-are, re-form-atus. Attach a suffix, and in three steps we have arrived at the Reformation (L re-form-at-io), a “re-shaping” that was one of the most profoundly important events in European history.

    Notice some of the delightfully regular features of the Latin denominative and its English descendants. A cause for rejoicing is the fact that the vast majority of these verbs belong to the FIRST CONJUGATION, a pattern that we know to be straightforward and predictable. What we’re dealing with, in effect, is the addition of -are, -atus to a vast number of Latin nouns. “To get into a mask” (L persona) is im-person-are, im-person-atus: to impersonate. As in this particular example, a great many of the English derivative verbs will end in -ate; that is to say, they will be derived from the 1st conjugation Latin perfect participle in -atus. Furthermore, as we saw in Chapter 10 (§71), it will be an incredibly easy step to turn that perfect participle into a noun: “the act of getting into a mask” is an im-person-at-io, English impersonation. Because the Latin noun that meant “wheel” was rota, the verb “to wheel” is rot-are, rot-atus, and we can fully understand the etymology of rotate and rotation (rot-at-io). You will likely be amazed at the number of English words that can be explained by those few obvious principles.

    Here are a few examples that use familiar noun vocabulary from Chapters 2 and 3:

    tabula (“list”) tabulare, tabulatus tabulate tabulation
    locus (“place”) locare, locatus locate location
    populus (“people) populare, populatus populate population
    stimulus (“spur”) stimulare, stimulatus stimulate stimulation
    terminus (“end”) terminare, terminatus terminate termination
    officium (“duty”) officiare, officiatus officiate
    vitium (“fault”) vitiare, vitiatus vitiate
    labor (“work”) e-laborare, e-laboratus elaborate elaboration
    milit– (“soldier) militare, militatus militate
    origin– (“source”) originare, originatus originate origination
    capit- (“head”) de-capitare, de-capitatus decapitate decapitation
    lumin– (“light”) il-luminare, il-luminatus illuminate illumination
    opus, oper– (“work”) operare, operatus operate operation
    gradu– (“step”) graduare, graduatus graduate graduation
    situ- (“position”) situare, situatus situate situation

    The English nouns in the fourth column, of course, all come from Latin nouns of the type tabulatio, tabulation-is; locatio, location-is, etc. Not every -io word of this kind actually existed in real Latin use, at any time in history; many of them were created in modern English (or French) as the result of inventiveness and analogy. (It is a curious and paradoxical fact of English that our language has more Latin derivatives than the sum total of all known Latin words!) In addition to producing the -io type nouns, Latin denominative verbs could be the source of AGENT NOUNS like terminator, originator, and operator, which maintain their exact Latin form in English. (§73).

    We could devise another long list of denominative verbs from familiar Latin adjectives. Firmus is the source of the verb con-firm-are, con-firm-atus and its derived noun con-firm-at-io (E confirmation); compare ad-firm-at-io > affirmation. Acceleration is derived from ad-celer-at-io (< celer, “fast”), and abbreviation from ad-brevi-at-io (< brevis, “short”). Alleviate (ad-levi-are) and aggravate (ad-grav-are) are etymological opposites, from levis (“light”) and gravis (“heavy”). These last few examples illustrate the principle of assimilation (< ad-simil-at-io). From longus come e-long-at-io and pro-long-at-io, (E elongation and prolongation.). The adjectival base of infatuated is fatu-us (“silly”); of desiccated, sicc-us (“dry”); and of extenuated,tenu-is (“thin”).
