Internet troublemaker initially explains young loony's off this? (7)
I believe the answer is:
trolley
'loony's off this?' is the definition.
The definition suggests a singular noun which matches the answer.
'internet troublemaker initially explains young' is the wordplay.
'internet troublemaker' becomes 'troll' (I've seen this in another clue).
'initially' suggests taking the first letters.
The initial letters of 'explains young' is 'ey'.
'troll'+'ey'='TROLLEY'
Can you help me to learn more?
(Other definitions for trolley that I've seen before include "Basket, truck on wheels" , "Yell rot (anag.)" , "Refreshments off this" , "tramcar" , "Wheeled table, cart" .)
