-ate

-ate

1
a suffix occurring in loanwords from Latin, its English distribution paralleling that of Latin. The form originated as a suffix added to a- stem verbs to form adjectives (separate ). The resulting form could also be used independently as a noun (advocate ) and came to be used as a stem on which a verb could be formed (separate; advocate; agitate ). In English the use as a verbal suffix has been extended to stems of non-Latin origin: calibrate; acierate .

Origin:
< Latin -ātus (masculine), -āta (feminine), -ātum (neuter), equivalent to -ā- thematic vowel + -tus, -ta, -tum past participle suffix

-ate

2
a specialization of -ate1, used to indicate a salt of an acid ending in -ic , added to a form of the stem of the element or group: nitrate; sulfate .
Compare -ite1.


Origin:
probably originally in Neo-Latin phrases, as plumbum acetātum salt produced by the action of acetic acid on lead

-ate

3
a suffix occurring originally in nouns borrowed from Latin, and in English coinages from Latin bases, that denote offices or functions (consulate; triumvirate; pontificate ), as well as institutions or collective bodies (electorate; senate ); sometimes extended to denote a person who exercises such a function (magistrate; potentate ), an associated place (consulate ), or a period of office or rule (protectorate ). Joined to stems of any origin, ate3, signifies the office, term of office, or territory of a ruler or official (caliphate; khanate; shogunate ).

Origin:
< Latin -ātus (genitive -ātūs), generalized from v. derivatives, as augurātus office of an augur (augurā(re) to foretell by augury + -tus suffix of v. action), construed as derivative of augur augur

Word Origin & History

-ate
suffix used in forming nouns from L. words ending in -atus, -atum (e.g. estate, primate, senate). Those that came to Eng. via O.Fr. and M.Fr. often arrived with -at, but an -e was added after c.1400 to indicate the long vowel. The suffix also can mark adjectives formed from L. past participals in -atus,
-ata (e.g. desolate, moderate, separate), again, they often were adopted in M.E. as -at, with an -e appended after c.1400.

-ate
verbal suffix for L. verbs in -are. O.E. commonly made verbs from adjectives by adding a verbal ending to the word (e.g. gnornian "be sad, mourn," gnorn "sad, depressed"), but as the inflections wore off English words in late O.E. and M.E., there came to be no difference between the adj. and the verb
in dry, empty, warm, etc. Accustomed to the identity of adjectival and verbal forms of a word, the English, when they began to expand their Latin-based vocabulary after c.1500, simply made verbs from L. pp. adjs. without changing their form (e.g. aggravate, substantiate) and thus it became the custom that L. verbs were Anglicized from their pp. stems.
