A splinter bid is a conventional bid that promises support for partner's suit while showing shortness (one or zero cards) in another suit. It is usually an unusual jump in a new suit. For example, over partner's 1H opening, a bid of 4C would be a splinter bid, showing four or more hearts and at most one club (plus the strength to be in game).
A bid in bridge replying to a partner's bid or double is a "response".
The recommended response to a 2 diamond opening bid in bridge is to bid 2 hearts if you have a weak hand, or bid 2 spades if you have a strong hand.
In bridge, a reverse bid is when a player bids in a higher-ranking suit than their first bid, showing strength and a longer suit in the second bid. This differs from a regular bid where the player bids in a lower-ranking suit or the same suit as their first bid.
A common preferred response to a weak 2 bid in bridge is to bid at the 2-level with a strong hand or to pass with a weaker hand.
The most common bidding response to an opening bid of 2 clubs in the game of bridge is a bid of 2 diamonds.
In the game of bridge, a bid of one no trump is typically considered forcing, meaning it requires further bidding from the partner.
Reverse bidding in bridge is a second bid, usually done by the opener at a two level or higher in a higher- ranking suit than the original bid. It's important to recognize a reverse when your partners does one.

What is a short club bid
If your bridge partner forces you to bid, make the best bid you can manage and don't worry about it. The responsibility is all on your partner. You never claimed to have a good hand. Trust your partner to have enough winning cards.
A negative double bridge bid is significant because it shows support for partner's suit and helps to communicate information about the strength and distribution of the hand. It is used to indicate a desire to defend against the opponents' bid and can help in making strategic decisions during the game.
