Passage ancient poet largely avoided in recitation (7)
I believe the answer is:
oviduct
'passage' is the definition.
(oviduct is a kind of passage)
'ancient poet largely avoided in recitation' is the wordplay.
'ancient poet' becomes 'Ovid' (Roman poet).
'largely' means to remove the last letter (most but not all of the letters).
'avoided' becomes 'ducked' (duck can mean to avoid).
'in recitation' indicates a 'sounds like' (homophone) clue (as it would sound if recited).
'ducked' sounds like 'duct'.
'ovid' with its last letter taken away is 'ovi'.
'ovi'+'duct'='OVIDUCT'
(Other definitions for oviduct that I've seen before include "route for egg delivery" , "Egg-laying tube" .)
