The quality or state of being domineering; arrogance, overbearingness, or tyrannical behavior.
From 'domineering' (present participle of 'domineer', from Dutch/Latin) + '-ness' (forming abstract nouns from adjectives). The '-ness' suffix creates an abstract noun expressing the quality of the adjective.
Words ending in '-ingness' tend to feel psychologically vivid—'domineeringness' doesn't just mean controlling others, it suggests an offensive personality trait, a character flaw, whereas the simpler 'domination' is morally neutral and just describes actions.
