Hypocrisy surrounding working issue in agreement (9)
I believe the answer is:
consonant
'in agreement' is the definition.
('consonant' can be a synonym of 'in agreement')
'hypocrisy surrounding working issue' is the wordplay.
'hypocrisy' becomes 'cant' (I've seen this before).
'surrounding' means one lot of letters goes inside another.
'working' becomes 'on'.
'issue' becomes 'son' (issue can mean someone's offspring).
'on'+'son'='onson'
'cant' going around 'onson' is 'CONSONANT'.
(Other definitions for consonant that I've seen before include "B, C, D or F, perhaps?" , "not I, nor you, one hears" , "sounding well together" , "In agreement" , "Letter; harmonious chord" .)
