lintel: [14] Lintel is the result of the blending of two Latin words: līmes ‘boundary’ (source of English limit) and līmen ‘threshold’ (source of English subliminal and possibly also of sublime). Līmen had a derived adjective, līmināris ‘of a threshold’. In the post-classical period, under the influence of līmes, this became altered to *līmitāris, which was used in Vulgar Latin as a noun meaning ‘threshold’. This passed into English via Old French lintier, later lintel.
