Answer:
If you are asking for the definition, it is a type of prayer that blesses God or asks God for blessing.
If you want an example:
בָּרוּךְ אַתָּה יְיָ אֶלוֹהֵינוּ מֶלֶךְ הַעוֹלָם שֵהֵחְיָנוּ וְקִיְמָנוּ וְהִגִיעָנוּ לַזְמַן הַזֶה׃
Baruch atah hashem elokeinu melech ha-olam shehecheyanu vekimanu vehigianu lazman hazeh.
Blessed are you, Eternal our God, ruler of the universe, who has given us life, sustained us, and allowed us to reach this occasion.
