Some reds maybe, as tree initially decays (5)
I believe the answer is:
trots
'some reds maybe' is the definition.
I can't tell whether this definition defines the answer.
'tree initially decays' is the wordplay.
'initially' suggests taking the first letters.
'decays' becomes 'rots' (rot is a kind of decay).
The first letter of 'tree' is 't'.
't'+'rots'='TROTS'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for trots that I've seen before include "Runs slowly" , "jogs" .)
