Face vocal Cockney has kissed (6)
I believe the answer is:
aspect
'face' is the definition.
(I know that face can be written as aspect)
'vocal cockney has kissed' is the wordplay.
I cannot quite understand how this works, but
'cockney has' could be 'as' ('has' said with a cockney accent, dropping the 'H') and 'as' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aspect that I've seen before include "'Scene, view, vista (6)'" , "'Appearance, facet (6)'" , "Appearance or viewpoint" , "Look, panorama" , "Point of view or appearance" .)
