What does duply mean?
Duply is an archaic English word meaning double or twofold. It was used to describe things made up of two corresponding parts, or obligations and quantities that occurred twice over, much as we would today use 'double' or 'twofold'. The word derives ultimately from the Latin 'duo', meaning two, placing it among the large family of English words built on that root, including 'dual', 'duel', 'duplicate', and 'duplex'. Although it once had genuine currency, duply has fallen entirely out of everyday use and survives only in historical documents, dialect glossaries, and comprehensive dictionaries. Readers encountering it today will most often find it in older legal or literary texts, where a duply debt meant one owed twice over. In modern writing it should be replaced by its living equivalents.
adjective (archaic/rare)An archaic and rare word meaning double or twofold in nature.
- Double; consisting of two corresponding parts or occurring twice over (archaic).
"The scribe recorded the debt as duply, owed twice over by the same hand."
"The contract imposed a duply obligation, binding each party to two separate payments."
"In older verse, the refrain was sung duply, echoing through both halves of the hall."
Before 'doubly' took over English, writers reached for this forgotten twin — a word so obscure it now survives mainly in the pages of old dictionaries.

Duply comes from the Latin root 'duo' ('two'), which entered English vocabulary largely through Old French forms beginning in 'du-'. It belongs to the same family as 'duple', 'dual', 'duplicate', and 'duplex'. The word is attested in earlier periods of English but has since become obsolete, displaced in ordinary usage by 'doubly' and related terms.
How duply is actually used
This word is archaic and effectively obsolete in contemporary English; it appears almost exclusively in historical texts, glossaries of dialect, and older dictionaries. Modern writing should use 'double', 'doubly', or 'twofold' instead.
