         b. The king of France is not bald.          c. Is the king of France bald?         d. If the king of France is bald, he should wear a hat in the winter .

a relationship that applies between two sentences/

propositions, where the truth of one implies the truth of the other

because of the meaning of the words involved

a relationship that applies between two sentences/

propositions, where the truth of one implies the truth of the other

Characteristic

• logical consequences following from what is asserted in the utterance

• Sentences, not speakers, have entailments

e.g. a) John beats Tom.

=> b) John beats someone.

c) Tom was beaten by someone.

a) true => b) & c) true

e.g. Mary loves her dog very much.

=> Mary loves an animal very much.

dog: hyponymy

animal: superordinate

Characteristic

• In one occasion, one sentence can has a number of background entailments but one foreground entailment.

• Foreground entailments which is defined by stress, is more important for interpreting intended meaning.

• e.g.

• Rover chased three squirrels.

=>Rover chased a certain number of squirrels.

• Rover chased three squirrels.

=>Someone chased three squirrels.
