A little squirt, perhaps (5)
I believe the answer is:
spray
'squirt perhaps' is the definition.
'spray' can be an answer for 'squirt' (thesaurus). I am not sure about the 'perhaps' bit.
'a little' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
The remaining letters 'spry' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spray that I've seen before include "posy of flowers" , "small bouquet of flowers" , "Squirt water" , "Drench" , "Spindrift, flower bunch" .)
