Batsman's first edge an unforeseen hitch (4)
I believe the answer is:
blip
'an unforeseen hitch' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'batsman's first edge' is the wordplay.
'batsman's first' becomes 'b' (lst letter of 'batsman').
'edge' becomes 'lip' (lip is a kind of edge).
'b'+'lip'='BLIP'
Can you help me to learn more?
(Other definitions for blip that I've seen before include "Small mark - unforeseen deviation" , "Temporary irregularity" , "Glitch" , "Short-lived deviation" , "Temporary exception" .)
