The words sack and sac sound the same but have different meanings and are spelled differently.
- Sac usually refers to a biological pouch or bag-like structure found in plants or animals. For example, the yolk sac in an egg is a sac.
- Sack is typically used for a non-biological container, often made of cloth, paper, or plastic. Think of a bag of groceries or a sack of potatoes.
Here are some examples to further illustrate the difference:
- Sac:
- Yolk sac: Holds the yolk of an egg.
- Air sac: Part of a bird's respiratory system.
- Gallbladder: A sac in the body that stores bile.
- Sack:
- Sleeping bag: Used for warmth while camping.
- Sack of flour: Used to store flour in a bakery.
- Mailbag: A bag used for carrying mail.
While both terms refer to containers, sac is primarily associated with biological structures, whereas sack is used for non-biological containers.
