Lumbered with school food (5)
I believe the answer is:
stuck
'lumbered' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'school food' is the wordplay.
I cannot quite see how this works, but
'school' could be 's' and 's' is located in the answer.
'food' could be 'tuck' (I've seen this before) and 'tuck' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for stuck that I've seen before include "Jammed" , "Fixed" , "Glued" , "Unable to move" , "Will's thrust" .)
