The document explains the grammatical usage of the phrases 'either/or' and 'neither/nor', outlining that 'either/or' presents a choice between two positive possibilities while 'neither/nor' indicates two or more negatives. It also provides rules for verb agreement based on whether the subjects are singular or plural and emphasizes the format for using 'not only/but also'. Additionally, there are practice questions to reinforce the concepts discussed.

EITHER OR VERSUS NEITHER
NOR

2. • Either / or: is used in a sentence when referring to a choice
between two possibilities.
• Neither / nor: is used in a sentence in a negative context when
you want to say that two or more things are untrue.
Clarify
• Both ''neither'' and ''either'' must be followed by a preposition that is
consistent with the meaning and intent of these words.
• Since ''neither'' conveys a negative, it must be matched with the
negative preposition ''nor'' whenever it is used a sentence.
-Neither is never paired with “or.”
•Since ''either'' denotes a positive and conditional meaning, it must be
followed by the positive conditional preposition ''or'' in a sentence.
- Either is never paired with “nor.”

3. Singular or plural
When using either/or and neither/nor, note the following rules:
1. If both elements are singular, then the verb is singular too.
• Either the father or the mother has to attend the meeting. (Father
and mother are singular; so the verb has is singular too)
• Neither Leila nor Nancy is going to write the report. (Leila
and Nancy are singular; so the verb is is singular too)
2. However, if one of the elements is plural, then use a plural verb.
• Either Sue or the girls are going to prepare dinner tonight. (The girls
are plural; so the verb is plural too)
• Neither the teacher nor the students were in the classroom this
morning. (The students are plural; so the verb is plural too)

4. Not only/but also
• When “not only” is followed by “but also” (or simply “but”), make sure the
parts that follow each set of words are formatted the same way.
• “not only” is followed by “but also” (or “but”)
Example: He is not only a great swimmer, but also a great musician. (Good
because the sentence uses two noun clauses, which are underlined.)
