'Polynyms', surely.

https://en.m.wikipedia.org/wiki/Barbarism_(linguistics)

I've never heard of 'Multinyms' but I am right in thinking they're just homophones ?

This is extremely dependent on dialect and accent, but they don't specify which one they're talking about.

> borough, burro, burrow

Nah, not 'round 'ere they ain't.

I also maintain a list of these. Here are some I don't see there:

greater grater grader

baron barren bearing

your cees, seas, sees, seize is missing cease

grisly grizzly gristly

pedal peddle petal

I also put since with cense, cents, scents, sense

steal steel still

peal peel pill

If you need help: Ewe mite higher too guise two bee yore assistance.

Some of these have different pronunciation (depending on accent?), e.g. parish vs perish

  Thanks to Warren Kinney for distinguishing the British pronunciation of "new" and "knew"

Multinyms, so words with multiple pronounciations/names?

Anyway, I'm not a native speaker, but e.g. air, are, e'er, ere, err, heir does not sound identical to me. The Oxford English Dictionary says: ɛː, ɑː/ə, ɛː, ɛː, əː, ɛː, which makes are and err different. Unfortunately, the author doesn't give a source, so it's probably just his dialect?

This reminds me of https://en.wikipedia.org/wiki/Buffalo_buffalo_Buffalo_buffal...

Edit: It's not on the list because its using multiple meanings of the same spelling...

Throw in regional accents and you’ll get many more! Aaron earned an iron urn: https://youtu.be/Esl_wOQDUeE?si=J34OmyDod7GHUrl1

Real eyes realize real lies.

> Sextuplets:

> air, are, e'er, ere, err, heir

When does "are" sound like the rest?

For: call, caul, col

Wot about: cawl ?

Many of these are totally pants/panz/pænts

I would add yaw/yore/your/you’re

air, are, e'er, ere, err, heir

I guess I need to go back to school because I pronounce some of them quite differently.
