Is it knitted with wire wool? (5,6)
I believe the answer is:
cable stitch
'is it knitted' is the definition.
I can't tell whether this definition defines the answer.
'with wire wool?' is the wordplay.
'with' says to put letters next to each other.
'wire' becomes 'cable' (synonyms).
'wool?' becomes 'stitch' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cable'+'stitch' is 'CABLE-STITCH'.
Can you help me to learn more?
(Other definitions for cable stitch that I've seen before include "Aran feature" , "Twisted rope design" , "knitting pattern" , "Knitting that's twisted" .)
