Hi,
I have found a few definitions on poker and would like to share with you all.
Poker Definitions –

Dealer: The Dealer is one who shuffles the cards and deals the cards to players. A dealer in online casinos is indicated with a dealer button.

Pocket card: A Pocket Card is one of the first two cards that were dealt by the dealer.

Community card: a card that is on the table and available for all players.

Small blind: The amount of chips that player to the left of the dealer has to bet, depending on stakes.

Big blind: The amount of chips that second player to the left of the dealer has to bet, depending on stakes.

Flop: The first three cards that are dealt on the table.

Turn card: This is the fourth card of the table. It is also called Fourth River

River card: This is the last and fifth card on the table.

Hand: ‘Hand’ are the five cards that the players collect from the pocket cards and the community cards.

Dealer button: This is a red button that indicates the dealer.

Showdown: This is a term for the end of the final betting round when all the active players turn their cards face up to see who has won the pot.

There are numerous other types of poker with slight differences as compared to the general poker rules, but the basic gameplay style is the same and it will just take a few hands even for a newbie to get along with the different types of pokers available in the UK online casinos.
Hope this is going to help you all. Thanks.
