Fingerprints of fishes? (4)
I believe the answer is:
dabs
This could be a double definition.
'fingerprints' is the first definition.
(dab can mean a fingerprint)
'fishes?' is the second definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps you can see a link between them that I can't see?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for dabs that I've seen before include "Fingerprints (slang)" , "fingerprint" , "they give evidence to police" , "Fingerprints (informal)" , "digitally recorded evidence" .)
