Etymology: The word "hypothesiser" is simply a spelling variant of "hypothesizer," and its history is a plain, step-by-step construction in English. It is built from "hypothesize," which in turn comes from "hypothesis" with the suffix "-ize." That suffix passed through Late Latin "-izare" and Ancient Greek "-izein," where it formed verbs meaning "to make into" or "to treat in a certain way," and it reached English through Old French and Middle English. The final piece, "-er," is an older English ending that has long attached to verbs to name the person who performs their action, as in "teacher" or "writer." Its roots run back through Old English "-ere" and Latin "-arius," a suffix denoting a person connected with something. Adding it to "hypothesize" yields a word for someone who hypothesizes, which is the sense the meaning describes: someone who puts forward ideas that still need testing.

Synonyms: theorist, speculator, formulator
