Take first pig round and into the hold (4)
I believe the answer is:
stow
'into the hold' is the definition.
I can't judge whether this defines the answer.
'take first pig round' is the wordplay.
'take first' becomes 't' (1st letter of 'take').
'pig' becomes 'sow' (I've seen this before).
'round' means one lot of letters goes inside another.
't' put within 'sow' is 'STOW'.
'and' is the link.
Can you help me to learn more?
(Other definitions for stow that I've seen before include "Place in storage receptacle" , "Author, -- Asimov" , "Store away tidily" , "Pack, put away" , "Keep under hatches" .)
