It's wrong to say "these is" since these can refer to a plural, "these are" is correct

as for pronunciation, most people will say:

  • "this": [this] and not [thiz].
  • "these": [theeze] (rhymes with cheese)

"this-iz" vs "theeze-iz"

Can I pronounce these sounds the same way, is it fine?
No. These two sounds are meaningfully different in English. Changing these sounds will make a word unintelligible. It doesn’t matter that we spell them with the same letters. More on reddit.com

Honestly, how do explain these pronunciation inconsistencies to learners without starting an etymology/history of English class? And without "it is what it is"?

April 15, 2023 - The word “this” uses the Short-i sound, and “these” uses the Long-E sound. These two sounds are very similar, but there is one key difference that many students of English do not know about. The key is tongue tension.

October 4, 2025 - The word "these", the plural form, begins with a strong TH sound as well, but then it's a high E - 'thee' 'thee'. So it's longer and tenser, 'thee'. And you end it with a 'z' sound, like a Z - 'theez'.
