Read the reading below carefully, then answer the questions: Meaning in language While the fields of language study mentioned above deal primarily with the form of linguistic elements, semantics is the field of study that deal with the meaning of these elements.

For instance, the sentences “ The dog bit the man ” and “ The man bit the dog ” contain exactly the same morphemes, but they have different meanings. This is because the morphemes enter into different constructions in each sentence, reflected in the different word orders of the two sentenses. 1.
