Etymology
Etymology Information

'duly' originates from English formation based on the adjective 'due' plus the adverbial suffix '-ly'; 'due' originates from Old French 'deu', ultimately from Latin 'debitus', where the Latin root 'debere' meant 'to owe'.

Historical Evolution

'duly' developed from Middle English use of 'due' (from Old French 'deu' and Latin 'debitus') combined with the suffix '-ly' to form an adverb meaning 'in a due manner', eventually becoming the modern English 'duly'.

Meaning Changes

Initially related to the idea of something 'owed' or 'due', it evolved to mean 'in a proper, appropriate, or timely manner' in modern usage.
