GIVE ME SOME SLACK
Still very much in use today and probably thought by most people as being relatively modern in origin, the phrase ‘give me some slack’ or ‘cut me some slack’ (meaning make allowances to complete something) is actually hundreds of years old. Tying a ship to a pier was no easy feat and took two teams of men armed with mooring lines. As one line was pulled to haul the ship closer the other line was released or ‘given slack’. The process would go on until the ship was properly aligned.
