Get together and tuck in (6)
I believe the answer is:
gather
This might be a double definition.
'get together' is the first definition.
(synonyms)
'tuck in' is the second definition.
'gather' can be an answer for 'tuck' (synonyms). I'm not certain of the 'in' bit.
'and' is the link.
Can you help me to learn more?
(Other definitions for gather that I've seen before include "Harvest or learn by inference" , "Accumulate, amass" , "Congregate" , "Collect together in one place" , "Bring or assemble together" .)
