Cut someone some slack

To be less harsh on someone; to give them leeway or extra understanding

Meaning

Cut someone some slack — To be less harsh or critical towards someone; to give them leeway, allowance, or extra understanding, especially when they are struggling or going through a difficult time.

Origin & History

The phrase has nautical origins. On a ship, 'slack' is the loose, untensioned part of a rope or line. When sailors give or cut slack, they loosen a rope so that it is no longer pulled tight — reducing the strain on it and on whatever it is attached to.

From this literal sense of loosening tension, the expression developed a figurative meaning during the 20th century: to ease the pressure on a person rather than a rope. To 'cut someone some slack' is therefore to relax your demands or criticism, giving them room to cope much as a loosened line gives a vessel room to move.
