Long to decorate? Not I! (4)
I believe the answer is:
pant
'long' is the definition.
(I've seen this before)
'decorate? not i' is the wordplay.
I cannot quite see how this works, but
'not' could be 'nt' (synonyms) and 'nt' is present in the answer.
'i' could be 'a' and 'a' is present in the answer.
A single letter 'p' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for pant that I've seen before include "Breathe noisily after running" , "Gasp for breath (like a hot dog?)" , "Sound out of breath" , "Breathe heavily" , "Breath rapidly" .)
