Pass out of recollection (3)
I believe the answer is:
col
'pass' is the definition.
(col is a term for a mountain pass)
'of recollection' is the wordplay.
'of' says the answer is hidden in the clue.
'COL' is hidden within 'recollection'.
'out' is the link.
(Other definitions for col that I've seen before include "A pass through ridge" , "A depression in mountain range" , "Low area between peaks" , "Depression among ecologists" , "Mountain defile" .)
