IPA: /ɪɡˈzɔːbɪtəntli/
KK: /ɪɡˈzɔːrbɪtəntli/
In a way that is much too high or excessive, often referring to prices or costs.
The hotel charged exorbitantly for a simple room during the holiday season.
Exorbitantly → It is formed from "ex-" (meaning out of or away from) and "orbitare" (meaning to wander or to circle). The word describes something that goes beyond the usual limits or bounds, hence excessively high or unreasonable.
Think of something that goes 'out of bounds' ('ex-') and 'wanders' ('orbitare') beyond what is normal — that's why exorbitantly means excessively high.
