The state or quality of being excited; heightened emotional or physical state.
From 'excited' (past participle of 'excite') + '-ness' (suffix forming abstract nouns). The '-ness' suffix comes from Old English and creates nouns expressing states or qualities.
While 'excitement' is far more common, 'excitedness' emphasizes the state or condition of being in an excited state—it's the feeling itself rather than the cause.
