Scuttle in very little water (4)
I believe the answer is:
tear
This clue might be a double definition.
'scuttle' is the first definition.
(thesaurus)
'very little water' is the second definition.
'tear' can be an answer for 'water' (thesaurus). I'm not sure about the 'very little' bit.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tear that I've seen before include "Split - career" , "Rip apart; drop" , "Small flaw, as in glass" , "Rip, pull apart" , "Rip; salty drop" .)
