indent: Etymologically, English has two separate words indent, although they have converged to a considerable extent over the centuries (particularly in the virtually shared derivative indentation). The one meaning ‘(make) a hole or depression’ [14] is simply a derivative of dent, which itself probably originated as a variant of dint. Indent ‘make notches in’ [14], however, owes its origin to Latin dēns ‘tooth’.

This formed the basis of an Anglo-Latin verb indentāre, which denoted the drawing up of a contract between two parties on two identical documents, which were cut along a matching line of notches or ‘teeth’ which could subsequently be rejoined to prove their authenticity. A particular use of such contracts was between master craftsmen and their trainees, who hence became known as indentured apprentices.
