Shallow end removed - it had to help? (10)
I believe the answer is:
facilitate
'help?' is the definition.
('facilitate' can be a synonym of 'help')
'shallow end removed it had' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
'had' could be 'ate' (e.g. I had an ice cream) and 'ate' is present in the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for facilitate that I've seen before include "Make easier" , "Ease" , "Make (something) easy" .)
