What does conduplication mean?
Conduplication is a rare English noun denoting the act or state of doubling something over upon itself, or, in rhetoric, the deliberate repetition of a word or phrase for emphasis. In botany, it describes structures such as young leaves whose halves are folded together along the midrib before they expand; in rhetoric, it names a figure of speech in which a speaker repeats a key word to reinforce an idea. The word derives from the Latin verb duplicare, meaning 'to make double,' itself built on duo ('two') and plicare ('to fold') — the same root behind 'duplicate' and 'duplicity.' Because of its technical origins, conduplication appears almost exclusively in scholarly prose: older botanical descriptions, classical rhetorical treatises, and specialized dictionaries. It is not part of everyday vocabulary, but it offers writers a precise term where ordinary words like 'repetition' or 'folding' would be less exact. Readers are most likely to meet it in historical scientific texts or in discussions of rhetorical figures alongside better-known terms such as anaphora and epizeuxis.
nounThe action of doubling something over upon itself, or the state of being so doubled; in rhetoric, the repetition of a word or phrase for emphasis.
- The act of doubling something over upon itself, or the condition of being folded double (used especially in botany of parts such as leaves).
- In rhetoric: the repetition of a word or phrase for emphasis or effect.
"The leaf's conduplication along its midrib protects the young tissue within."
"In many monocots the young leaf shows conduplication, each half folded against the other along the midrib."
"The orator's conduplication of the word 'never' left no doubt about his conviction."
The plural is regular and rare, typically used when referring to multiple instances of folding or repetition across different specimens or passages.
"The monograph catalogued conduplications observed in several species of grasses."
Before it described folded leaves and repeated phrases, conduplication carried the same Latin root that gives us 'duplicate' and 'duplicity' — literally 'folded into two.'

Etymology of conduplication
Conduplication comes from late Latin conduplicatio, formed from the prefix com- with duplicare, 'to make double,' from duo ('two') plus plicare ('to fold'). The same Latin root produced the English cognates 'duplicate,' 'duplicity,' and 'double.' The word entered English usage in scholarly contexts, appearing in botanical and rhetorical writing from roughly the seventeenth century onward.
How conduplication is actually used
A rare, technical term encountered chiefly in older botanical writing and in treatments of classical rhetoric. It carries no emotional connotation and belongs to formal, scholarly registers rather than everyday speech.
