Please contribute for arch (5)
I believe the answer is:
'arch' is the definition.
(I know that ogive is a type of arch)
'please contribute' is the wordplay.
'please' becomes 'o' (form of address eg in an ode).
'contribute' becomes 'give' (synonyms).
'for' is the link.
(Other definitions for ogive that I've seen before include "pointed window" , "Lancet arch" , "Feature of Gothic church" , "Pointed or Gothic arch" , "Mount --, Washington's home" .)
