Having the right to open up, as a self-employed person (9)
I believe the answer is:
freelance
'a self-employed person' is the definition.
(synonyms)
'having the right to open up' is the wordplay.
'having the right' becomes 'free' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to open up' becomes 'lance' (lancing is a kind of opening up).
'free'+'lance'='FREELANCE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for freelance that I've seen before include "Not tied to employer" , "Of journalist, one who works for several employers, self-employed" , "without regular work?" , "Independent" , "Writer or artist who sells services to different employers" .)
