straight-sided
|straight-saɪ-dɪd|
/ˈstreɪt.saɪ.dɪd/
sides are straight
Etymology
'straight-sided' is a compound formed from the adjective 'straight' + the noun/combining form 'side' plus the adjectival suffix '-ed'; 'straight' originates from Old English 'stræht' (past participle of a verb meaning 'to stretch') meaning 'not bent' and 'side' originates from Old English 'sīde' meaning 'flank, lateral surface'.
'straight' came from Old English 'stræht' (related to verbs meaning 'to stretch'), and 'side' from Old English 'sīde'; the compound 'straight-sided' developed in post-medieval/Modern English by combining these elements to describe objects with straight sides.
Initially the elements meant 'stretched/straight' and 'side/edge'; together they have long been used to mean 'having straight sides,' a literal descriptive meaning that has remained largely stable.
