spine: spine: [14] Spine comes via Old French espine from Latin spīna ‘thorn’, which was probably derived from the same base as spīca ‘ear of corn’ (source of English spike ‘pointed flower head’). The metaphorical extension ‘backbone’ developed in Latin, perhaps via ‘prickle’ and ‘fish bone’. A spinney [16] is etymologically a ‘thorny thicket’. The word comes via Old French espinei from Vulgar Latin *spīnēta, an alteration of Latin spīnētum ‘thorny hedge’, which was derived from spīna.
