I need help in defining the exact meaning of "alkoxycarbonylation"
as the word carbonylation refers to introduction of carbonyl
so when I say alkoxycarbonylation, that should mean the introduction of alkoxy carbony

[MahaMohsen]

I know it is simple as carbonylation refers to the introduction of carbonyl, so does this apply to the same meaning

[pgk]

Yes! Somehow, the same.
“Alkoxycarbonylation” means the introduction of an ester group to a (usually) hydrocarbon chain.
RH → RCO2R’
As you suppose, the nomenclature derives from alkoxy- (R’O-) + carbonyl- (-CO-) = -CO2R’
PS: This is a spectroscopy forum and not the neighboring, pure organic chemistry one.
