Give money to personnel all year initially (3)
I believe the answer is:
pay
'give money' is the definition.
(paying someone is giving them money)
'personnel all year initially' is the wordplay.
'initially' indicates taking the first letters.
The initial letters of 'personnel all year' is 'PAY'.
'to' is the link.
(Other definitions for pay that I've seen before include "Profit" , "Screw" , "Hand over money for" , "Financial reward" , "stop possible leaks on board" .)
