Sense: noun/1
'Felicitation' is a very formal word for expressing pleasure at someone's success or another happy event. 'Congratulations' is the usual everyday choice and sounds natural in speech, cards, and quick messages. 'Good wishes' is broader: it can be used for birthdays, travel, or recovery, even when no achievement is involved. 'Compliments' can mean polite praise, but it does not usually focus on a happy occasion in the same way. Use 'felicitation' mainly in ceremonial, literary, or official contexts.
