Irritable way to engrave in tidy limits (6)
I believe the answer is:
tetchy
'irritable' is the definition.
(I know that irritable can be written as tetchy)
'engrave in tidy limits' is the wordplay.
'engrave' becomes 'etch' (I've seen this in another clue).
'in' is an insertion indicator.
'limits' suggests removing the centre.
'tidy' with its middle taken out is 'ty'.
'etch' inserted into 'ty' is 'TETCHY'.
'way to' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tetchy that I've seen before include "Touchy" , "Irritable, cross" , "Cantankerous" , "Ratty" , "Easily provoked" .)
