What is another word for self-righteously?
Pronunciation: [sˈɛlfɹˈa͡ɪt͡ʃəsli] (IPA) 
Self-righteously is an adverb that describes behavior in a pompous manner, as if one is morally superior. There are several synonyms for this word, including sanctimoniously, holier-than-thou, haughtily, and arrogantly. Sanctimoniously emphasizes the hypocritical nature of such behavior, suggesting that the person is pretending to be more virtuous than they really are. Holier-than-thou conveys the same sense of superiority, but implies that the person is judging others based on their own standard of goodness. Haughtily and arrogantly imply a more general sense of overbearing pride and may be used to describe behavior beyond the moral realm. All of these words capture the negative connotations of self-righteousness and are useful for describing the behavior when it occurs.
