Make an impression in Turkey’s borders, being irritable (6)
I believe the answer is:
tetchy
'irritable' is the definition.
(synonyms)
'make an impression in turkey's borders' is the wordplay.
'make an impression' becomes 'etch' (I've seen this before).
'in' means one lot of letters goes inside another.
'borders' says to hollow out the word (remove centre letters) (only the edge or border letters remain).
'turkey' with its middle removed is 'ty'.
'etch' placed inside 'ty' is 'TETCHY'.
'being' is the link.
(Other definitions for tetchy that I've seen before include "Easily irritated or annoyed, narky" , "Easily provoked" , "Irritable, cross" , "Cantankerous" , "liable to blow a fuse" .)
