IPA: /ˌdɪsəˈbiːdiəntli/
KK: /dɪsəˈbiːdiəntli/
In a way that shows a lack of obedience or refusal to follow rules or instructions.
The child disobediently ignored his parents' warnings.
Disobediently → It is formed from "dis-" (meaning apart or away) and "obedient" (from Latin "obedientem", meaning to obey). The suffix "-ly" indicates manner. Thus, "disobediently" means in a manner that is apart from or away from obedience.
Think of 'dis-' meaning apart and 'obedient' meaning to obey — so disobediently means acting in a way that is not obeying.
