Definition of "gratulatory"

The blissful day over, and the happy bride and bridegroom withdrawing from the banquet and the dance, the well-pleased chirping, able little tutor hopped before them, and led them to the hymeneal bower with floral flute, and gratulatory song!"

1844, Various, Blackwood's Edinburgh Magazine, No. CCCXLV. July, 1844. Vol. LVI.‎

A roar of gratulatory triumph broke--a roar so loud and inspiring that for a moment the densely packed masses did not distinguish an ear-splitting outburst just in front of them.

1898, Henry Francis Keenan, The Iron Game‎

The air was full of laughter and greetings and kisses; light-hearted, offhand, gratulatory kisses which appeared to be the natural currency of felicitation.
