The quality, practice, or ideology of being a devotee; excessive or zealous devotion to something or someone.
From 'devotee' + -ism (suffix meaning 'system, practice, or ideology'). The -ism suffix typically denotes movements, philosophies, or behavioral patterns.
The -ism suffix is how English converts individual behaviors into whole philosophies—so 'devoteeism' transforms personal worship into a systematic, almost ideological commitment.
