Derived from the French verb 'envelopper', meaning to wrap up or envelop, combining the prefix 'en-' (in) and 'velopper' (to wrap, of uncertain Germanic or Celtic origin). It entered the English language in the late 16th century initially as a verb, later evolving into the standard noun for a paper container used for letters.
