Attractive engineer getting on (8)
I believe the answer is:
engaging
'attractive' is the definition.
('engaging' can be similar in meaning to 'attractive')
'engineer getting on' is the wordplay.
'engineer' becomes 'eng'.
'getting on' becomes 'aging' (I've seen this before).
'eng'+'aging'='ENGAGING'
(Other definitions for engaging that I've seen before include "Fighting - winning" , "Attractive; employing" , "Interesting" , "Attractive or charming - getting married?" , "coming into battle" .)
