Stellate comes straight from the Latin adjective stellātus, formed from the noun stella “star” and –ātus, a suffix that forms adjectives from nouns. The noun stella comes from an unrecorded stēr–lā or stēr–o–lā. Stēr– comes from a very widespread Proto-Indo-European root ster-, stēr– “star,” appearing in Sanskrit star-, Germanic (English) star. Greek preserves the most ancient form, astḗr, the a– being the remainder of a Proto-Indo-European laryngeal consonant. Stellate entered English at the end of the 15th century.

Scaturient is a very rare adjective meaning “bubbling up, gushing forth.” It comes from Latin scaturrient-, scāturient-, the participle stem of scaturriēns, scāturiēns, from the verb scaturrīre, scatūrīre. The Latin verbs are derivatives of scatēre, scatere “to gush violently”; the suffix –urīre is of obscure origin and usually forms desiderative verbs (verbs that express the desire to perform the action denoted by the underlying verb). The Latin root scat– is a derivative of the Proto-Indo-European root skēt– “to jump, spring, hop,” source of Old Lithuanian skasti “to jump, spring,” and perhaps of English shad (the fish), from Old English sceadd. Scaturient entered English in the latter half of the 17th century.
