  3. 3

    1769, Bible, Authorised King James Version
    Note

    Here the word means money owed rather than a way of behaving. The King James Bible sets it beside tribute in Romans: 'tribute to whom tribute is due; custom to whom custom.' The singular is uncountable, meaning payment in general. The plural customs names the duties themselves, which are what the verb for paying duties takes as its business.

    Similarusage

    Note

    Lawyers keep this sense apart from its near-synonym usage. The legal writer Francis Wharton drew the line sharply: 'usage is a fact and custom is a law', so there can be usage without custom but never custom without usage. Its authority comes from long consent rather than from any enactment, which is why it invites comparison with prescription.

Origin

"Custom" came from Middle English custume, borrowed from Anglo-Norman custume, which came from Latin consuētūdinem, a noun from cōnsuēscō (con- "with" plus suēscō "become used or accustomed to"). It is a doublet of costume and consuetude, and the adjective form first appears around 1830.
