Suction broken by very posh bloke (8)
I believe the answer is:
viscount
'posh bloke' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'suction broken by very' is the wordplay.
'broken' indicates an anagram.
'by' means one lot of letters go next to another.
'very' becomes 'v' (abbreviation).
'suction' is an anagram of 'iscount'.
'iscount' after 'v' is 'VISCOUNT'.
Can you help me to learn more?
(Other definitions for viscount that I've seen before include "Minor peer" , "Nobleman" , "British peer" , "plane" , "Lord" .)
