The quality of being express; the state of being clearly stated, direct, or unmistakably communicated.
From 'express' (from Latin expressus, 'pressed out') plus the suffix '-ness' meaning 'state or quality of.' The idea of being 'pressed out' evolved to mean clearly stated or explicitly shown.
Expressness is what you value when someone gives you a straight answer instead of beating around the bush—it's the opposite of vagueness, and languages that value directness tend to use this word more often.
