Entry 3 - SPEECH ACTS

J. Austin distinguishes constatives and performatives as two different parts of the speech.
Constatives are sentences that describe something as true or false; while performatives are sentences that denotes actions.
Some words are actions and they are called speech acts; examples of that are ordering, promising, apologizing, warning, sentencing or marrying.
Performatives must be authoritative, understood, clear and able to be executed for the act to be a felicity condition.
