[372]. Some frequentatives in -tāre are formed from the present stem of a verb in -ere; the formative vowel before -tāre becomes i: as,
agi-tāre, shake (age-re); flui-tāre, float (flue-re); nōsci-tāre, recognize (nōsce-re); quaeri-tāre, keep seeking (quaere-re); scīsci-tārī, enquire (scīsce-re); vēndi-tāre, try to sell (vēnde-re).
[373]. A few frequentatives add -tā- to the perfect participle stem: as,
ācti-tāre, act often (ācto-); facti-tāre, do repeatedly (facto-); lēcti-tāre, read again and again (lēcto-); ūncti-tāre, anoint often (ūncto-). From a frequentative another frequentative is sometimes derived: as, dict-āre, dictate, dicti-tāre, keep asserting (dicto-).
[374]. Some verbs are found only as frequentatives: as, gust-āre, taste (*gusto-, √gus-, taste); put-āre, think (puto-, √pu-, clean); aegrōt-āre, be ill (aegrōto-).
[375]. A few verbs in -uriō, -urīre, express desire; such are called Desideratives: as, ēss-urīre or ēs-urīre, want to eat (edere, ēsse). A few in -ssō, -ssere, express earnest action; such are called Meditatives: as, lacē-ssō, lacē-ssere, provoke.
[COMPOSITION.]
[376]. In compounds, the fundamental word is usually the second, which has its meaning qualified by the first.
[377]. A Direct Compound is one formed directly from two parts: as, con-iug-, N. coniūnx, yoke-fellow (com-, together, √iug-, yoke); con-iungere, join together (com-, iungere); an Indirect Compound is one formed by the addition of a suffix to a direct compound: as, iūdic-io-, N. iūudicium, trial (iūdic-): iūdicā-re, judge (iūdic-).
[378]. A Real Compound is a word whose stem is formed from two stems, or an inseparable prefix and a stem, fused into one stem; an Apparent Compound is formed by the juxtaposition of an inflected word with another inflected word, a preposition, or an adverb.
