You start to stagger after immediately standing (6)
I believe the answer is:
status
'standing' is the definition.
(I've seen this in another clue)
'you start to stagger after immediately' is the wordplay.
'you' becomes 'u' (homophones).
'start to' suggests taking the first letters.
'after' says to put letters next to each other.
'immediately' becomes 'stat' (short for Latin statim).
The first letter of 'stagger' is 's'.
'u'+'s'='us'
'us' after 'stat' is 'STATUS'.
(Other definitions for status that I've seen before include "Social position or grade" , "Rank or position in society" , "Importance, standing" , "Social position - prestige" , "Social ranking" .)
