It may cure sick little computer (6)
I believe the answer is:
tablet
'computer' is the definition.
'it may cure sick little' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
'little' could be 'l' (abbreviation for little) and 'l' is located in the answer.
'sick' could be 'be' (synonyms) and 'be' is present in the leftover letters.
The remaining letters 'at' 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 tablet that I've seen before include "Medicine - flat slab - computer" , "pill needed" , "Prescription" , "PC" , "A small pill or an inscribed panel on wall" .)
