Love yarn clothing young swimmer (7)
I believe the answer is:
tadpole
'young swimmer' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tadpole that I've seen before include "Frog in formation" , "Young frog" , "developed from spawn" , "Old tape (anag.)" , "young swimmer" .)
