Usage

What is a basic definition of deck? The word deck is used as a noun to refer to a floorlike surface on a ship, an unroofed porch attached to a house, or a pack of playing cards. Deck has many other senses as a noun, verb, and adjective. On a ship, a deck is a surface that acts as a floor that the crew is able to walk on. A ship can have more than one deck depending on size, so terms like upper deck, main deck, and lower deck may be used to tell them apart.

• Real-life examples: The RMS Titanic was a large ship that had 10 decks. A pirate captain may order a crewman to swab, that is, mop, the deck.
• Used in a sentence: I walked with the ship’s captain across the Promenade deck. 

When referring to a house, a deck is a roofless porch or platform that extends from the house itself. A deck can have many functions, such as providing a surface for outdoor furniture or a barbeque grill.

• Real-life examples: A house built in a place with frequent sunny weather might have a sun deck that is a good spot for sunbathing or relaxing. A home with a swimming pool may have a pool deck that connects to the house so people can easily walk to the pool.
• Used in a sentence: We sat on the deck and watched the fireworks.

A pack of playing cards is also called a deck. In the United States, a standard set of playing cards has 52 cards in four suits—spades, hearts, diamonds, and clubs.

• Real-life examples: Poker and blackjack are games that require a deck of cards. A fortune teller often uses a deck of tarot cards to tell fortunes.
• Used in a sentence: The dealer drew the ace of diamonds from the deck.

Etymology

Origin of deck

First recorded in 1425–75; (for the noun) late Middle English dekke “material for covering,” from Middle Dutch dec “covering, roof”; (for the verb) from Dutch dekken “to cover”; cognate with German decken; cf. thatch

Explanation

A deck is a platform or a section of floor on a ship. If you're on a cruise with your family, you might tell your brother to meet you on the upper deck after lunch to play shuffleboard. Most decks are open, without a roof, and positioned high on a ship . Typically, the bridge deck houses the ship's helm and navigational tools. The deck behind your house isn't much different from a ship's deck — it's a flat platform too. Other kinds of decks are a pack of cards, the board part of a skateboard, and the floor: "Hit the deck!" To deck a person is to hit them, but to deck your house is to decorate it.
