The public notice fair, competent and fit to be adapted (10)
I believe the answer is:
adjustable
'fit to be adapted' is the definition.
I can't judge whether this defines the answer.
'the public notice fair competent' is the wordplay.
'the public notice' becomes 'ad' (short for advertisement).
'fair' becomes 'just' (Synonym).
'competent' becomes 'able' (similar in meaning).
'ad'+'just'+'able'='ADJUSTABLE'
'and' is the link.
Can you help me to learn more?
(Other definitions for adjustable that I've seen before include "Able to be adapted" , "Modifiable" .)
