Eat up and roll in yet another drinks cart (3,7)
I believe the answer is:
tea trolley
'drinks cart' is the definition.
'tea trolley' can be an answer for 'cart' (tea trolley is a kind of cart). I'm unsure of the 'drinks' bit.
'eat up and roll in yet another' is the wordplay.
'up' indicates an anagram (letters get chucked up).
'and' is a charade indicator (letters next to each other).
'in' means one lot of letters goes inside another.
'another' indicates an anagram.
'yet' anagrammed gives 'tey'.
'roll' going into 'tey' is 'trolley'.
'eat' with letters rearranged gives 'tea'.
'tea'+'trolley'='TEA-TROLLEY'
Can you help me to learn more?
(Other definitions for tea trolley that I've seen before include "From which a waiter might serve" , "Server of refreshments" , "It brings drinks" .)
