It might be helpful in grabbing something to eat (5)
I believe the answer is:
talon
'it might be helpful in grabbing something to eat' is the definition.
The definition suggests a singular noun which matches the answer.
'it might be' is the wordplay.
'it' becomes 't' (abbreviation. e.g. in 'tis).
'might be' becomes 'alon' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'alon'='TALON'
Can you help me to learn more?
(Other definitions for talon that I've seen before include "Tonal (anag.)" , "Bird of prey's claw" , "Holding part of flier" , "Hooker" , "Hooked claw; cards left after deal" .)
