As a weapon, is there something fishy about it? (4)
I believe the answer is:
pike
'as a weapon is there something' is the definition.
I can't tell whether this definition defines the answer.
'fishy about it?' is the wordplay.
'fishy' becomes 'kip' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' says the letters should be written in reverse.
'it?' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'kip' backwards is 'pik'.
'pik'+'e'='PIKE'
Can you help me to learn more?
(Other definitions for pike that I've seen before include "jackknife" , "Weapon on long shaft; Northern hill" , "See 1 down" , "Old weapon -- Dad's Army character" , "Spearhead attached to a long pole" .)
