To pray is to talk to a deity or god. Some people pray by asking for help or guidance.
Most religious believers pray in one way or another — some pray out loud, thanking God for the things they have. Others pray silently when they're afraid or worried, or in a group of worshipers at a church or temple. You can also pray in a non-religious way, by begging for something: "I pray you'll really listen to my explanation." Pray comes from the Old French preier, "to pray," with its Latin root word, precari, "ask earnestly, beg, or entreat."
