Fish spreads from innards? (4)
I believe the answer is:
rays
'fish spreads from innards?' is the definition.
'rays' can be an answer for 'fish' (I've seen this before). I'm not certain of the 'spreads from innards?' bit.
'fish spreads' is the wordplay.
'fish' becomes 'ray' (ray is a kind of fish).
'spreads' becomes 's' (this could be a standard abbreviation of which I'm unaware).
'ray'+'s'='RAYS'
Can you help me to learn more?
(Other definitions for rays that I've seen before include "Beams of sunlight" , "Beams from sun or moon" , "Columns of light or heat" , "Single lines of light" , "Narrow beams of light" .)
