Spotted Jack starting in Galway making shapes with blade (6)
I believe the answer is:
jigsaw
'galway making shapes with blade' is the definition.
I can't judge whether this definition defines the answer.
'spotted jack starting' is the wordplay.
'spotted' becomes 'saw' (I've seen this in another clue).
'jack' becomes 'jig' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'starting' says to put letters next to each other.
'saw' after 'jig' is 'JIGSAW'.
'in' is the link.
Can you help me to learn more?
(Other definitions for jigsaw that I've seen before include "Puzzle fittingly completed" , "Puzzle-maker" , "Sharp tool (for cutting puzzle into pieces?)" , "Picture in pieces" , "Kind of puzzle" .)
