One salutes someone or something. For example, Here's to Bill on his retirement, or Here's to the new project. This phrase, nearly always used as a toast to someone or something, is a shortening of here's a health to and has been so used since the late 1500s. Shakespeare had it in Romeo and Juliet (5:3): "Here's to my Love."
