Identify the type of negation in the following sentences. Justify your choice in a phrase or sentence. i They aren’t at home. ii Mr. Mittal has misplaced the file. iii None of the singers was up to the mark. iv A little knowledge is a dangerous thing. v Why haven’t they been invited.

Let's identify the type of negation in each of the sentences and provide justification:

i. They aren’t at home.

• Type of Negation: Simple negation (using "not")
• Justification: The word "aren't" is a contraction of "are not," which straightforwardly negates the statement that they are at home.

ii. Mr. Mittal has misplaced the file.

• Type of Negation: Affixal negation (using "mis-")
• Justification: The word "misplaced" is formed by adding the prefix "mis-" to "placed," indicating a negation or incorrect placement of the file.

iii. None of the singers was up to the mark.

• Type of Negation: Negative quantifier (using "none")
• Justification: The word "none" is a negative quantifier that indicates not any or no singers were up to the mark.

iv. A little knowledge is a dangerous thing.

• Type of Negation: Indirect negation (using "little" to imply lack)
• Justification: The phrase "a little knowledge" implies a small amount or lack of extensive knowledge, indirectly suggesting a negative connotation about the extent of knowledge being dangerous.

v. Why haven’t they been invited.

• Type of Negation: Interrogative negation (using "haven't")
• Justification: The use of "haven't" in an interrogative sentence forms a negative question, asking why they have not been invited, thereby implying the absence of an invitation.

In summary, these sentences demonstrate different types of negation including simple negation, affixal negation, negative quantifier, indirect negation, and interrogative negation, each serving to express negation or absence in varying linguistic forms and contexts.
