jetty

Origin

The noun is derived from Late Middle English gete, jette, jetti (“projecting upper storey of a building, overhang; breakwater, pier, jetty”), from Anglo-Norman geté, getee, getté, and Middle French geté, getee, jeté (“projecting upper storey of a building; breakwater, pier”) (modern French jetée), a noun use of the past participle of geter, jeter, from Old French geter, jeter (“to throw”) from Late Latin iectāre, the present active infinitive of iectō (“to throw”), probably from Latin iactō (“to cast, hurl, throw”), from iaciō (“to cast, hurl, throw”) (ultimately from Proto-Indo-European *(H)yeh₁- (“to throw”)) + -tō (frequentative suffix). Compare jet (“(obsolete) protruding part”), jutty. The verb is derived from the noun.
