Maybe branches hang on over generations (10)
I believe the answer is:
appendages
'maybe branches hang on over generations' is the definition.
I can't tell whether this definition defines the answer.
'hang on over generations' is the wordplay.
'hang on' becomes 'append' (synonyms).
'over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'generations' becomes 'ages' (I've seen this in another clue).
'append'+'ages'='APPENDAGES'
Can you help me to learn more?
(Other definitions for appendages that I've seen before include "they're hanging on" , "supplements" , "things going on" .)
