@Pamela1960 "In the case of the English 'boot', the origin is that in the 18th and 19th centuries, the coachman used to sit on a locker where he could store, among other things, his boots. For this reason, this was termed the 'boot locker' and after a while an additional compartment situated at the rear of the coach was used, also called for the same reason the 'boot' (for short)."https://english.stackexchange.com/questions/15934/stick-it-in-the-boot-er-dont-you-mean-the-trunk
