Stand, carrying a single wide hamper (9)
I believe the answer is:
stonewall
'hamper' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'stand carrying a single wide' is the wordplay.
'stand' becomes 'stall' (synonyms).
'carrying' means one lot of letters goes inside another.
'a single' becomes 'one' (a single thing - only one).
'wide' becomes 'w' (abbreviation e.g. in cricket).
'one'+'w'='onew'
'stall' going around 'onew' is 'STONEWALL'.
Can you help me to learn more?
(Other definitions for stonewall that I've seen before include "Check" , "Obstruct by refusing to answer questions" , "delay in parliament" , "Delay or block (a proposal's) progress" , "Obstruct or hinder any discussion" .)
