the word 'striate' originates from the latin 'striatus', the past participle of 'striare', meaning to groove or to flute. this verb itself is derived from 'stria', denoting a furrow, channel, or linear groove. the latin 'stria' is thought to be related to the proto-indo-european root streig-, meaning to stroke or rub, which also gives rise to words like 'strigil' and 'streak'. the semantic journey is direct, moving from the physical act of creating lines or grooves to the resulting state of being marked with such lines, a meaning preserved in both its verb and adjective forms in modern english.
