 Many forms of implicature are not figures of speech, and have become widely recognized only since Grice (1975). (1)  illustrates relevance implicature: the speaker implicates an answer to an expressed or implied question by stating something related to it by implication or explanation.  [5b]  is a quantity (or scalar) implicature: the speaker implicates the denial of a proposition stronger than the one said.  (6)  illustrates ignorance implicature: the speaker implicates that something stronger than what was said is unknown.  (7)  illustrates metalinguistic implicature: the speaker implicates that something has a certain name by using that name to describe it. These "modes of speech" (non-figurative forms of implicature) are not taught in school, and names for them are not in general use. Nevertheless, they are as frequent and natural as figurative speech, and are learned at the same time. Modes of speech are not marked intonationally, and the speech is literal. They are not used to make speech or writing lively. Speakers do not intend what they say to be obviously false, and generally do mean what they say.
