assertive

Etymology

Etymonline and Dictionary.com take it as formed from English assert + -ive,^[2][3] and Webster's Third and Merriam-Webster from assertion with the same suffix.^[4][5] The Shorter Oxford takes it instead as borrowed from French assertif, from Medieval Latin assertīvus,^[6] while the OED treats the Latin word as unrecorded and compares Middle French assertivement in Cotgrave and Italian assertivo in Florio.^[7] The English verb comes from Latin assertus, the past participle of asserō (“to claim, lay claim to”), formed from ad (“to”) and serō (“to join together, put in a row”), from Proto-Indo-European *ser- (“to line up”).^[2][6]

Earliest recorded meaning

Of the nature of assertion; declaratory, positive: 1562, in a letter of the Bishop of Exeter printed in Strype's Annals of the Reformation.^[7][2] Merriam-Webster dates the word to about 1619, and the Shorter Oxford to the early 17th century.^[5][6]

Semantic evolution

At first the word described statements: declaratory, positive, dogmatic.^[7][2] Johnson (1755) defined it as "positive; dogmatical; peremptory", quoting Glanvill.^[8] In logic it was used from 1849 for what rests on mere assertion.^[7] The modern sense, "insisting on one's rights or opinions", is short for self-assertive, according to Etymonline, and the phrase assert oneself is recorded from 1879.^[2] Collins separates a favourable sense, confident and direct in claiming one's rights, from an unfavourable one, dogmatic or aggressive.^[9] Merriam-Webster also applies it to a wine or a food with a strong, distinctive flavour or aroma.^[10]
