-ata (e.g. desolate, moderate, separate), again, they often were adopted in M.E. as -at, with an -e appended after c.1400.
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.
