To cover or treat with oil; to anoint or oil something.
From Old French 'enoillier', derived from 'en-' (in, on) + 'oil', with roots going back to Latin 'oleum' (oil), used in English from the 13th century.
Medieval texts use 'enoil' in religious and medical contexts—priests would 'enoil' the sick and dying with sacred oils for healing and last rites, making it a word charged with spiritual meaning.
