Flipping secretary hiding in one tree or another! (5)
I believe the answer is:
maple
'or another' is the definition.
I can't judge whether this definition defines the answer.
'flipping secretary hiding in one tree' is the wordplay.
'flipping' is a reversal indicator.
'secretary' becomes 'pa' (abbreviation for personal assistant).
'hiding in' means one lot of letters goes inside another.
'one tree' becomes 'elm' (elm is a kind of tree).
'pa' placed within 'elm' is 'elpam'.
'elpam' reversed gives 'MAPLE'.
Can you help me to learn more?
(Other definitions for maple that I've seen before include "Syrup-yielding tree" , "Tree yielding syrup" , "Syrup-producing tree" , "Tree; sugar from it" , "Tree with winged seeds" .)
