Start to change locks for one in charge of meeting (5)
I believe the answer is:
chair
'one in charge of meeting' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'start to change locks' is the wordplay.
'start to' indicates taking the first letters.
'locks' becomes 'hair' (locks can mean hair).
The first letter of 'change' is 'c'.
'c'+'hair'='CHAIR'
'for' is the link.
Can you help me to learn more?
(Other definitions for chair that I've seen before include "Official position of authority" , "academic office" , "Seat for one person" , "director at meeting" , "Professorship" .)
