The tasty bits contributed by Murphy? (5)
I believe the answer is:
chips
'murphy?' is the definition.
(I know that chips is a type of potato)
'the tasty bits contributed by' is the wordplay.
'the tasty' becomes 'hips' (I can't justify this - if you can you should believe this answer much more).
'bits' says to take the initial letters (I've seen 'bits of' mean this).
'by' means one lot of letters go next to another.
The first letter of 'contributed' is 'c'.
'hips' after 'c' is 'CHIPS'.
Can you help me to learn more?
(Other definitions for chips that I've seen before include "Common accompaniment to fish" , "Flakes" , "fried in 18 [MAIZE OIL] perhaps" , "Betting counters" , "Goodbye, Mr. ---; --- with Everything" .)
