Got stuck into light food to start with (7)
I believe the answer is:
tackled
'got stuck' is the definition.
Although both the answer and definition are past participle verbs, I can't see how they can define each other.
'light food to start with' is the wordplay.
'light' becomes 'led' (abbreviation for light emitting diode).
'food' becomes 'tack' (informal term for food).
'to start with' says to put letters next to each other.
'led' after 'tack' is 'TACKLED'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for tackled that I've seen before include "Confronted" , "Took on, set about dealing with" , "Grappled with" , "dealt with" , "Intercepted (in soccer)" .)
