The quality or state of being amorous; the tendency to feel or show romantic love.
From amorous plus -ness, an Old English suffix meaning 'condition or quality.' The root amor from Latin gives this word its fundamental meaning of love.
The suffix '-ness' is English's favorite tool for turning feelings into nouns—it lets poets and writers talk about abstract emotions like 'amorousness' as if they're actual things you can examine and describe.
