IPA: /ˈɛksələnsɪ/

The state or quality of being exceptionally good or superior in some way.

**Excellency** → It is formed from "ex-" (meaning out of or from) and "celsus" (meaning high or lofty). The word "excellency" refers to a state of being high or superior in rank or quality, often used as a title of respect for high-ranking officials.
Think of someone being 'out of' ('ex-') the ordinary and 'high' ('celsus') in status — that’s why we use 'excellency' to refer to someone of high rank.
