Amative is an adjective whose complete definition one dictionary is ‘synonym of amorous’. It is used to describe something or someone has feeling or pertaining to love or lust. However, amorous may be used to describe someone or something as in love, which amative does not do.
The adverb form is amatively. The noun form is amativeness.
Amatory is also an adjective that can be a synonym for amorous. However, amatory deals more specifically with physical intimacy, instead of the more amorphous emotional love.
Amatory is slightly more popular that amative (especially considering our spell-checker doesn’t even consider it a word), but amorous is used the most often, by a wide margin.
