Projections for a leading proposal remain undecided a very long time (10)
I believe the answer is:
appendages
'projections' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'a leading proposal remain undecided a very long time' is the wordplay.
'leading' says to take the initial letters.
'remain undecided' becomes 'pend' (I've seen this before).
'a very long time' becomes 'ages' (ages can mean a very long period).
The initial letter of 'proposal' is 'p'.
'a'+'p'+'pend'+'ages'='APPENDAGES'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for appendages that I've seen before include "supplements" , "things going on" , "they're hanging on" .)
