Dai (Chinese:代; pinyin:Dài) was a short-lived state from 227 BC to 222 BC during the Warring States period. Prince Zhao Jia, older brother of King Youmiu of Zhao, fled with the remnant forces to the former location of Dai after the Conquest of Zhao and proclaimed himself "King of Dai". It was conquered in the year 222 BC by Qin.

In logic, a logical connective (also called a logical operator) is a symbol or word used to connect two or more sentences (of either a formal or a natural language) in a grammatically valid way, such that the sense of the compound sentence produced depends only on the original sentences.
The most common logical connectives are binary connectives (also called dyadic connectives) which join two sentences which can be thought of as the function's operands. Also commonly, negation is considered to be a unary connective.
A logical connective is similar to but not equivalent to a conditional operator.
In language
Natural language
In the grammar of natural languages two sentences may be joined by a grammatical conjunction to form a grammaticallycompound sentence. Some but not all such grammatical conjunctions are truth functions. For example, consider the following sentences:
Reading have been removed from their EFL embargo after publishing their financial accounts over 12 months late ... Other companies connected to Dai Yongge, such as RFCBearwoodLimited, also posted their accounts ... .
News reporters now stand in front of giant screens with vivid pictures of some place or person connected to the story being presented. These presenters then walk to a table or dais in the middle of the set to turn over the next story to a cohort ... ....
