Latin Forms:

Most English words, even those adapted from Latin, form derivatives or related words through pretty standard English rules. Test (noun) corresponds to test (verb); screen (noun) corresponds to screen (verb); president (noun) corresponds to presidential (adjective); determine (verb) corresponds to determination (noun).

But rule (noun) corresponds to regulate (verb). (Regulation also corresponds to regulate, but rule [noun] doesn't generally correspond to rule [verb].)

Crown (verb) corresponds to coronation (noun). (Though "crowning" [noun] is attested in the OED, it's extremely unusual; "coronation" is what is normally used.)

Dean (noun) corresponds to decanal (adjective), not to "deanic" or "deanal."

English (adjective) corresponds to Anglicize (verb), not to "Englishify."

See (verb) corresponds to visible (adjective), not to "seeable"; likewise for hear and feel. [UPDATE: As several commenters pointed out, this violates my rule 2 below; I added that rule -- to limit the range of possible answers -- after composing this set of examples, but forgot to come back to delete them. Whoops.]

What other correspondences like this can you find? The criteria are that (1) an Anglicized word must correspond to a Latinate form — (2) a form that shares the same Latin root as the Anglicized original (so "cat" / "feline" won't count) — and (3) must not correspond to a common alternative form created using relatively standard rules of English word adaptation.

Crown (verb) corresponds to crown (noun).
Coronate (verb) corresponds to coronation(noun).

Am I missing something, or are we just looking for synonmys and comparing the verb form of one with the noun form of the other?

Not much of a Latin scholar, alas.

May I muddy the waters? Does it matter whether the word came direct from Latin (e.g. through Church or University) or came via Norman French?

Treaties and wars between two countries seem to often by named by using the Latin form of the first country's name.

Franco-Prussian War
Anglo-French Entente
Anglo-Irish Treaty
Sino-Japanese War
Sino-Indian War
Sino-British Joint Declaration

This pattern does not seem to hold for events to which the US is a party, unless the other party is England:
Spanish-American War
Mexican-American War

Aren't you breaking your own rule #2 with the "see/hear/feel" examples? "See" and "visible" don't "share[] the same Latin root," nor do "hear" and "audible," nor do "feel" and "sensible" (or "tactile" or whatever you're thinking of).
5.17.2007 2:35pm
uh clem,
That's not quite right: crown (noun) is not in fact a synonym for coronation. And I don't think "coronate" is a real verb. So if you want a noun referring to the action of crowning someone (not the object they are crowned with), the only word is coronation.

I'm a little embarrassed that I can't think of many other examples. The best I can come up with is bishop --> episcopal, and I don't know how many people use "episcopal" in that sense. (Also, I'm not certain that it comes to English through Latin, rather than directly from Greek.

enemy --> inimical

@uh clem Are you sure "to coronate" is a word at all? It seems like back-formation to me. One can find uses of it here and there, but generally from people who weren't aware that "to crown" is the preferred form.
5.17.2007 2:42pm
I notice also that EV's last few examples don't follow his own rule 2: "see" is not from the same Latin root as "visible," and the same goes for "hear" and "feel."

Does it count if the Anglicized original comes not from a Latin root, but from the same Indo-European root as the Latin word? If so, ear --> aural, nose --> nasal and mind --> mental would work.
5.17.2007 2:46pm
right (adjective) --> rectitude (though maybe "rightness" is common enough to make this violate rule 3)
5.17.2007 2:51pm
space --> spatial

touch --> tactile

(Both of these inspired by the posts of Christopher M, who also, I see, beat me to the point about EV violating his own rule)

Coronate may be a back formation, but it's certainly a word.

Agree that coronation(noun) and crown(noun) are not synonmys, but crown(verb) and coronate(verb) are, assuming you accept "coronate" as a verb.

Oh, rats. Christopher M beat me to lion/leonine and eagle/aquiline.

Guessing here as I have no Latin, but maybe spleen/splenetic? River/riparian?

Then there are those oddball adjectival forms of British cities: Liverpool/Liverpudlian, Glasgow/Glaswegian. I remember wondering once whether they'd taken a side detour through Latin in the Roman period.

Are you sure that "rule" (n) and "rule" (v) don't go together? "Rule" and "regulate" are a modern pair, but there's a long tradition of governments that make all the rules and then rule with an iron fist. We don't think in those terms in a republic, but the correspondence still works as far as the language is concerned. The fact that we have "regulate" for a different shade of meaning is interesting, because it shows that one noun can match up with several verbs.

Similarly, we have "act" (n) and "act" (v), but we also have "activate" (not so far off the normal English rules) and "actuate" (downright bizarre).

Mother, father, brother, and sister don't clearly come from Latin, although the adjectival forms listed above do, thus violating one of EV's rules in the original post.

Correction: Whhether or not a "crowning" is rare, the verb "crown" corresponds a noun that's very common indeed. It's the thing that sits on the monarech's head.
5.17.2007 8:13pm
There are often distinct sets of Anglo-Saxon Anglo-Norman, Latin, and Greek words for the same thing, thus
king —-> kingly
roy —-> royal
rex/regina —> regal

Sometimes one element of a set drops out of common usage while others remain. Roy is very rarely used, yet royal remains common

Several of the examples in the later comments don't actually follow the rules. For example, not-Connie's "root (n) > radical (adj.)" "Radical" comes from Latin radix, to be sure, but "root" does not come from that "same Latin root," as Rule #2 requires. It doesn't come from a Latin root at all, but from Old Norse. (See The relevant Norse word is related to Latin radix, but it doesn't come from it: they're cousins, so to speak.

Karl Narveson (mail):
What Eugene noticed, with his examples rule/regular and crown/coronation, was the pattern linguists call a doublet. A doublet is a pair of words ((or word components) with the same source, but different transmission histories, leading to a difference in form. Double is itself a doublet with the "dupl" in duplicate or duplicity.

It doesn't require Latin to get a doublet - examples can be entirely English, like slick/sleek or break/breach. But Latin is a great source of doublets because so many Latin words were preserved in written texts while also being handed down in speech from parents to children over many centuries. To get more examples like Eugene's, just start with a word from Norman French, look up its Latin origin, and check for direct borrowings from the Latin.

tense/temporal (grammatical terms)
entire/integral (both are adjectives, but it's a valid doublet)
avenge/vindicate (both are verbs)

Connie (mail):
Karl--I thought "doublets" were when we use two words to mean the same thing (often found in law), such as cease &desist, null &void, aid &abet. English evolved like this because we took one word from French and one from Latin: different words that nonetheless had essentially the same meaning.

I think it must be another instance of lawyer-isolation (as with conclusory/conclusive) behind the sense that 'rule' as a verb is very rare. Even in law, a judge will rule that such and such is the case. We don't speak of legislators ruling, but we do speak of kings ruling. But I don't think we usually even speak of legislators regulating, not in ordinary English. Ordinary English speakings speak of legislators passing laws.

But that's another instance of the original phenomenon. Congress doesn't law. It legislates.
