Oh the anchor's a-weigh, the anchor's a-weigh, Fare-well, fare you well, my own true love
At last we parted on the shore, As the tears rolled gently from her eyes. Must you leave me now, she did say, That I face this all alone?
Oh the anchor's a-weigh, the anchor's a-weigh, Fare-well, fare you well, my own true love

“Aweigh” (or “a-weigh”) means the anchor has been lifted clear of the sea bottom—the ship is no longer anchored and is free to sail. The term comes from “to weigh anchor,” meaning to raise it. This is commonly confused with “away,” but “aweigh” specifically describes the moment the anchor breaks free from the bottom.

Another British naval song that seems to date from the wars before 1815.
