congratulator
One offering felicitations
A congratulator is someone who offers congratulations—expressing praise or good wishes for an achievement or happy occasion.
The word is uncommon; people typically use the verb or noun forms instead: She congratulated him rather than She was his congratulator.
When it does appear, it's often in contexts with multiple well-wishers: A line of congratulators waited to shake the graduate's hand.
