In various places in Ireland as well as elsewhere (4,3,5)
I believe the answer is:
here and there
'in various places' is the definition.
('here and there' means in various locations)
'ireland as well as elsewhere' is the wordplay.
I cannot quite understand how this works, but
'as well' could be 'and' (I've seen this in other clues) and 'and' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for here and there that I've seen before include "in several places" , "In various places" , "Sporadic localities?" .)
