Keep possession of bad tea in row (6)
I believe the answer is:
detain
'keep possession' is the definition.
'detain' can be an answer for 'keep' (I've seen this before). I'm unsure of the 'possession' bit.
'bad tea in row' is the wordplay.
'bad' indicates an anagram.
'in' indicates putting letters inside.
'row' becomes 'din' (both can mean a loud disturbance).
'tea' anagrammed gives 'eta'.
'eta' going inside 'din' is 'DETAIN'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for detain that I've seen before include "Keep waiting or under restraint" , "put in jail" , "Hold back or keep under restraint" , "Keep back or arrest" , "Keep in custody; hold back" .)
