tentative

Pronunciation

• /ˈtɛntətɪv/^[1]

Etymology

It is borrowed from Medieval Latin tentātīvus (“trying, testing”),^{[2][3][4][5][6]} from tentātus, the past participle of Latin tentō (“to feel, try”),^[3][5][4] a variant of temptō (“to handle, try, test”),^[2][5][7] with the suffix -īvus.^[8][9] Scholastic Latin also used tentātīva as a noun, and French has the noun tentative (“examination, attempt”) from the 16th century.^[2] For the Latin verb, Etymonline cites de Vaan's reconstruction Proto-Indo-European *tempto-, perhaps from a root meaning "to stretch".^[3]

Earliest recorded meaning

Of the nature of an experiment or trial; done provisionally: 1588, in J. Harvey's Discoursive Probleme concerning Prophesies.^[2] Barnhart finds the date implied in the adverb tentatively,^[10] and Hoad dates the adverb to the 16th century and the adjective to the 17th;^[6] Merriam-Webster's first date is 1626.^[9][11]

Semantic evolution

The word began in learned use, close to the Latin "trying, testing": Johnson (1755) defined it as "trying; essaying", quoting Berkeley's "This is not scientifical but tentative."^[12] From "made as a trial" it came to mean "provisional, not yet settled", as of plans or agreements,^[13][11][14] and, of people and their actions, "hesitant, uncertain".^{[15][13][11][14]} As a noun, an experiment or attempt, it is recorded from 1632,^[2][9] after the French noun.^[2]
