What musicians perhaps did in heavy traffic at the seaside? (6)
I believe the answer is:
jammed
'what musicians perhaps did in heavy' is the definition.
I can't judge whether this definition defines the answer.
'traffic at the seaside?' is the wordplay.
'traffic' becomes 'jam' (I have seen 'awful traffic' mean 'jam' so perhaps 'traffic' could also mean 'jam').
'at' says to put letters next to each other.
'the seaside?' becomes 'med' (I can't explain this - if you can you should believe this answer much more).
'jam'+'med'='JAMMED'
Can you help me to learn more?
(Other definitions for jammed that I've seen before include "crushed" , "in a confined space" , "Immovably stuck" , "Pressed tightly together, crammed" , "packed" .)
