I'm not an expert in linguistics but I do know how my mouth and tongue works! I apologise that I can't give examples in Cyrillic.

This word is roughly pronounced "ick", "thee", "oh", "fuh", "thirius". The surprising thing in English is the ph-th bit - we only see that in Greek words and perhaps some Russian or other Cyrillic based borrow words.

When I look at it, we English use two letters for each of these phonemes: ph (fuh) and th (thuh). In Cyrillic I think you have a single letter: phi and theta (Greek) - I don't know the actual Russian names but it will be similar.

We can say fuh/thuh in a word as consecutive phonemes but it is rare.

Interesting! I thought it would be the "ch-thy" part since "ch" usually sounds "t-sh"-ish in English, like "child".

I wonder if in English this phoneme uses the "k" sound only for words like "chrysanthemum" or "chrysalis" borrowed from Greek-ish languages.

Actually "ф" is just "ph" as in Philadelphia and "т" is "t", very close to how it sounds in the word "term". I think the key difference is that the "th" (sounds like in "the", "they", etc.) phoneme is a separate letter so it's decoupled from "t".

Nah, closer to "ick-thee-off-thirius": https://www.merriam-webster.com/medical/ichthyophthirius

Right, especially not having a vowel between them, because "f" -> "th" without an intervening vowel is very unusual in English.
