10-15 min read
A1 - A2 Level
Includes Examples

Either / Neither / Both

Both, either, and neither are three determiners used exclusively when talking about two things. "Both" includes the two together, "either" selects one of two, and "neither" excludes both. This A2–B1 lesson covers both, either and neither exercises with answers — practise either...or, neither...nor, and both...and grammar exercises online with multiple choice questions and printable PDF worksheets.

To use these words correctly, you need to understand 3 Words for 2 Things:

Word Meaning Noun Verb Example
both The two together ✅✅ plural plural Both restaurants are good.
either One or the other ✅❓ singular singular Either restaurant is fine.
neither Not one, not the other ❌❌ singular singular Neither restaurant was good.

Each word has 3 uses that you'll learn in this lesson:

Use Both Either Neither
Determiner + noun both roads either road neither road
Of-structure both of them either of them neither of them
Correlative conjunction both ... and either ... or neither ... nor

Remember: these three words are for exactly two items. For three or more, use all, every, or each instead.


Both, Either and Neither: Basic Meaning

Both = The Two Together

Both means "this one AND that one" — it includes two things as a pair. It takes a plural noun and a plural verb:

  • Both children are at school today.
  • I've been to Paris and Rome. I loved both cities.
  • Both parents came to the school concert.

Both can also stand alone as a pronoun:

  • I tried on two coats and both look good on me.
  • I have two sisters and both live in London.

Either = One or the Other

Either means "this one OR that one" — it offers a choice between two. It takes a singular noun and a singular verb:

  • We can watch either film — you choose.
  • You can sit on either side of the table.
  • Either day works for me. (Monday or Tuesday)

As a short answer, "either" means "I don't mind which one":

  • Would you like tea or coffee? — Either is fine.

Neither = Not One, Not the Other

Neither means "not this one AND not that one" — it excludes both. It takes a singular noun and a singular verb:

  • Neither restaurant was good.
  • I asked two people, but neither person could help me.
  • I tried on two jackets, but neither fitted me well.

As a short answer, "neither" rejects both options:

  • Is your birthday in May or June? — Neither. It's in July.

Both vs Either vs Neither: Quick Comparison

Situation Word Example
Two films, you liked them both I liked both films.
Two films, you'll watch one either We can watch either film.
Two films, you didn't like them neither Neither film was good.

Both of, Either of and Neither of

When you need to specify which two things you mean, use the of-structure: word + of + determiner/pronoun + plural noun.

The Of-Structure

Pattern Example Verb
both of + the/my/these + plural noun Both of the restaurants are good. plural
both of + pronoun Both of them agreed. plural
either of + the/my/these + plural noun Either of the options sounds good. singular (formal)
either of + pronoun Could either of you help me? singular (formal)
neither of + the/my/these + plural noun Neither of the answers is correct. singular (formal)
neither of + pronoun Neither of us understood the lecture. singular (formal)

Verb agreement rule:

  • Both of → always plural verb: Both of them are ready.
  • Either ofsingular verb (formal): Either of them is fine.
  • Neither ofsingular verb (formal): Neither of them is correct.

Note: In informal English, "neither of" and "either of" sometimes take a plural verb ("Neither of them are ready"), but the singular form is considered more grammatically correct.

Mid-Position Both

Both can move to a mid-position in the sentence — after be, after auxiliaries/modals, or before main verbs:

Position Example
After be My sister and I are both studying medicine.
After auxiliary The twins have both finished their homework.
After modal My brothers can both speak three languages.
Before main verb We both enjoy going to the cinema.

Mid-position "both" means the same as "both of us/them" but sounds more natural in speech:

  • ✅ We both enjoy hiking. (natural)
  • Both of us enjoy hiking. (correct but more formal)

Correlative Conjunctions: Both...and, Either...or, Neither...nor

These are fixed pairs (correlative conjunctions) that connect two parallel elements — subjects, objects, adjectives, or verbs.

Both ... and (Inclusive Positive)

Both...and links two things together, meaning "the first AND the second":

  • Both Tom and I enjoy hiking.
  • She speaks both French and Spanish fluently.
  • The hotel room was both clean and comfortable.

Both...and always takes a plural verb when linking two subjects:

  • Both the students and the teacher enjoyed the trip.

Either ... or (Choice)

Either...or presents two alternatives, meaning "the first OR the second":

  • You can either walk or take the bus.
  • I'm free on either Tuesday or Wednesday.
  • Either you clean your room or you can't go out tonight.

Neither ... nor (Double Negative)

Neither...nor excludes both options, meaning "not the first AND not the second":

  • Neither John nor Sarah was at the meeting.
  • The gift was neither expensive nor useful.
  • She neither called nor sent a message.

⚠️ The Pairing Rule: Never Mix Them

Each word has exactly one partner:

✅ Correct Pair ❌ Wrong Mix
both ... and both ... or, both ... nor
either ... or either ... and, either ... nor
neither ... nor neither ... or, neither ... and

The most common error is "neither...or" — always use "neither...nor".

Verb Agreement: The Nearest Subject Rule

With either...or and neither...nor, the verb agrees with the nearest subject (the one closest to the verb):

Sentence Nearest Subject Verb
Neither Tom nor his friends are coming. friends (plural) are
Neither his friends nor Tom is coming. Tom (singular) is
Either you or your brother needs to sign. brother (singular) needs
Neither my brother nor I am good at cooking. I am

With both...and, the verb is always plural (because "both" includes two):

  • Both my mother and my father work in the hospital.

Choosing the Right Word: Decision Guide

Quick Decision Tree

Step 1: Are you talking about exactly two things?

Step 2: What's your meaning?

Meaning Choose Example
The two together (positive) both I like both options.
One or the other (choice) either Either option is fine.
Not one, not the other (negative) neither Neither option works.

Step 3: What structure do you need?

Need Pattern Example
Before a noun both/either/neither + noun Both roads lead there.
With "the/my/them" word + of + determiner/pronoun Neither of them is correct.
Linking two elements both...and / either...or / neither...nor Either you or I will go.

Side-by-Side Comparison

Feature Both Either Neither
Meaning Two together One of two None of two
Noun Plural Singular Singular
Verb Plural Singular Singular
Of-structure ✅ both of ✅ either of ✅ neither of
Conjunction pair both ... and either ... or neither ... nor
Conjunction verb Always plural Nearest subject Nearest subject
As pronoun ✅ Both are good. ✅ Either is fine. ✅ Neither was good.

Common Mistakes to Avoid

Incorrect Correct Why Learners Make This Mistake
❌ Neither the food or the service was good. ✅ Neither the food nor the service was good. Mixing up "or" and "nor" — "or" is the partner of "either," not "neither." The fixed pair is always "neither...nor"
Both restaurant is good. Both restaurants are good. Forgetting that "both" needs a plural noun and plural verb — unlike "either" and "neither," which take singular
❌ Neither of them are correct. (formal writing) ✅ Neither of them is correct. Using a plural verb after "neither of" — in formal English, "neither of" takes a singular verb
Either Tom and I will go. Either Tom or I will go. Mixing up the conjunction partner — "either" pairs with "or," not "and"
Neither the teacher nor the students is ready. Neither the teacher nor the students are ready. Forgetting the nearest-subject rule — the verb agrees with "students" (nearest to the verb), not "teacher"
Both of options are good. Both of the options are good. / Both options are good. Missing the determiner in "of" structures — "both of" needs "the/my/these" before the noun

Quick Summary

The Framework: 3 Words for 2 Things

Word Meaning + Noun + Of Conjunction
both Two together both + plural both of the/them both ... and
either One of two either + singular either of the/them either ... or
neither None of two neither + singular neither of the/them neither ... nor

3-Step Decision Process

  1. Two things? → both/either/neither (for 3+ → all/every/each)
  2. Positive / Choice / Negative? → both / either / neither
  3. Structure? → determiner + noun / of + determiner / conjunction pair

Verb Agreement Rules

Structure Rule Example
Both + plural noun Plural verb Both roads are safe.
Either/Neither + singular noun Singular verb Either road is safe.
Both of + plural Plural verb Both of them are here.
Either of / Neither of Singular verb (formal) Neither of them is here.
Both ... and Plural verb Both Tom and I enjoy hiking.
Either ... or / Neither ... nor Nearest subject agreement Neither Tom nor his friends are coming.

Practice Tips

  1. Remember the fixed pairs: Both goes with "and," either goes with "or," neither goes with "nor." Never mix them — this is the #1 error with these words.

  2. Think "two": Both, either, and neither are only for exactly two items. If you're talking about three or more, switch to all/every/each or any/none.

  3. Check your noun number: Both + plural noun ("both roads"). Either/Neither + singular noun ("either road"). Getting the noun wrong often leads to a verb agreement error too.

  4. Master the nearest-subject rule: With "neither...nor" and "either...or," the verb matches the subject closest to it. Put the plural subject last to avoid awkward constructions: "Neither the teacher nor the students are..." sounds more natural than "Neither the students nor the teacher is..."

  5. Practise short answers: "Either is fine," "Neither," and "Both" are very common in everyday conversation when responding to two-option questions.
