Either / Or, Neither / Nor

Either This, Or That

A closer look at either / or and neither / nor — choices, rejections, and how to add another negative point smoothly.

Notice it

Choosing a payment gateway vendor

A:Have you decided which vendor we're going with for the payment gateway integration?
B:Not yet. Honestly, either option could work — Stripe or the local provider. Both meet our compliance requirements.
A:I'd lean toward Stripe, though. The local provider neither confirmed the SLA terms nor sent a finalized contract.
B:True. And I don't fully trust either of them with the security audit timeline.
A:Same here. Neither has passed a full penetration test yet.
B:So what do we do — escalate to the vendor management team, or just delay the sprint?
A:I think either choice pushes the release back, but escalating seems safer.
B:Agreed. The client didn't approve the extended budget, and neither did compliance sign off on the new terms.
A:Right, so we can't move forward with either plan until that's resolved.
B:Exactly. Let's raise it in tomorrow's stand-up — otherwise neither of us can commit to a release date.
Work it out

Questions about the conversation

1.Find every sentence with "either." Which ones offer a real choice, and which one means "not one, not the other"?
2.Look at "The local provider neither confirmed the SLA terms nor sent a finalized contract." What two facts are being joined, and what do you notice about the verb forms after "neither" and "nor"?
3.Look at "And neither did compliance sign off on the new terms." What's unusual about the word order right after "neither"? Compare it to a normal statement: "Compliance didn't sign off..."
4.Compare "Neither has passed a full penetration test" and "Neither did compliance sign off." Why does one use "has" and the other use "did... sign off"?
5.Find "I don't fully trust either of them." Could this sentence be rewritten with "neither... nor"? Try it, and compare the tone.
Examples and rules

How either and neither work

1. either ... or — a choice between two (positive)

Presenting or choosing between two real options.

We can use either Stripe or the local provider.
You can ship the fix either today or first thing tomorrow.
2. neither ... nor — rejecting both (negative)

The sentence is already negative — no extra "not" is needed, and this structure tends to sound more formal or written than "didn't... or".

The vendor neither confirmed the SLA nor sent a contract.
Compare, more casual: The vendor didn't confirm the SLA or send a contract.
3. either / neither alone — referring back to two known things
"Which vendor do you prefer?" — "Honestly, either is fine."
"Which environment should we cut?" — "Neither — we need both for testing."
4. neither / nor to add another negative point (inversion)

When you want to add a second negative fact to one already mentioned, "neither" or "nor" can start the new clause — but the word order flips, just like in a question: auxiliary before the subject.

The client didn't approve the budget. Neither did compliance sign off on the terms.
The release wasn't on schedule, nor was it fully tested when it shipped.
This inversion pattern is common in status reports, postmortems, and more formal spoken English — it sounds more polished than starting a new sentence with "And also not...".
5. "not ... either" — the everyday alternative

In casual speech, it's often easier to just add "either" to the end of a negative sentence — no inversion required.

The vendor didn't call, and they didn't email either.
Same meaning, more formal: The vendor didn't call, nor did they email.
6. verb agreement with "neither of / either of"

The verb agrees with the noun closest to it. With "neither of / either of + plural noun," a singular verb is correct in careful writing, though a plural verb is common in speech.

Neither of the environments has passed the audit. (formal)
Neither of the environments have passed the audit. (common in speech)
When "either... or" or "neither... nor" joins two different subjects, the verb agrees with the one nearer to it: Neither the vendor nor the developers were informed.
Controlled practice

Fill in the gap

Complete each sentence with either or neither.

Part 1 — Choices and options
Part 2 — Rejections and negative facts

Build the sentence

Put the words in the right order — some include the inversion pattern. Try it yourself first, then tap to check.

Speaking practice

1. Either way

Take turns offering a real work choice — two tools, two environments, two vendors, two release dates, anything from your actual work or an invented scenario. Your partner responds honestly: naming one, saying "either is fine," or rejecting both with "neither."

  • Do at least 5 rounds.
  • Use "either... or" with two named things at least twice.
  • At least once, reject both options and explain why with "neither."

2. The incident report

Partner A reports an incident (an outage, a failed deployment, a data mismatch) that went wrong in two separate ways. Partner A must describe both failures in one sentence using "neither... nor." Partner B, playing the incident lead, offers two possible fixes using "either... or."

  • Partner A: at least 2 different incidents, each described with "neither... nor."
  • Partner B: at least 2 fixes offered with "either... or" for each incident.
  • Switch roles with a new, invented incident.

3. Add the second negative

Partner A makes a negative statement about a real or invented work situation. Partner B must add a second, related negative fact using the inversion pattern — "Neither did..." or "Nor was..." — not just "and also not."

  • Do at least 4 rounds.
  • Use the inversion pattern each time, not the easier "not... either."
  • If you get stuck on word order, say the sentence slowly and check the auxiliary comes right after "neither/nor."
One rule: after each round, restate the same idea the easier way — with "not... either" — so you can hear both versions side by side.

4. Stakeholder update

Partner A gives a short project status update to a stakeholder (Partner B), mixing good and bad news. Any failures or missed items must be phrased with "neither... nor." Partner B asks at least 2 follow-up questions, then Partner A proposes a way forward using "either... or" to offer two options.

  • The update should cover at least 3 points (timeline, budget, scope, quality — pick any).
  • At least 1 point must use "neither... nor" to describe a shortfall.
  • The way-forward proposal must offer exactly two options with "either... or."

5. Sprint retro

Run a short two-person sprint retrospective. Each partner says one thing the team did well, then one thing neither of you managed to finish, using the inversion pattern ("Neither did we finish..."). Then together, agree on one change for next sprint by offering each other two options with "either... or" until you agree.

  • Each partner gives at least 1 "went well" and 1 "neither did we" point.
  • Reach agreement on next steps using "either... or" — don't just pick the first option offered; negotiate a little first.
