Party passionate about current venture initially requiring many workers (6-9)
I believe the answer is:
labour-intensive
'party passionate' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'current venture initially requiring many workers' is the wordplay.
I cannot quite understand how this works, but
'current' could be 'in' ('in' can mean current or trendy) and 'in' is located in the answer.
'many' could be 'ten' (ten of something) and 'ten' is found within the answer.
'workers' could be 'labour' (I've seen this before) and 'labour' is located in the answer.
This explanation may well be incorrect...
'about' is the link.
Can you help me to learn more?
(Another definition for labour-intensive that I've seen is " Involving much work".)
