Devote, consecrate (8)
I believe the answer is:
dedicate
I believe this is a double definition.
'devote' is the first definition.
(I know that devote can be written as dedicate)
'consecrate' is the second definition.
(I know that consecrate can be written as dedicate)
(Other definitions for dedicate that I've seen before include "Commit" , "Devote to a sacred person or use" , "Devote (to), pledge (to)" , "Devote, address, to" , "Devote to a special purpose, say time or energy" .)
