Snag involving equipment, originally cutting-edge? (2-4)
I believe the answer is:
hi-tech
'cutting-edge?' is the definition.
(I've seen this in another clue)
'snag involving equipment originally' is the wordplay.
'snag' becomes 'hitch' (synonyms).
'involving' is an insertion indicator.
'originally' says to take the initial letters.
The first letter of 'equipment' is 'e'.
'hitch' enclosing 'e' is 'HI-TECH'.
(Other definitions for hi-tech that I've seen before include "(Using) the latest developments" , "Style of interior design using features of industrial equipment" , "Advanced technology" , "latest devices" , "Involving the latest electronic gadgetry" .)
