How to Pronounce Psoriasis Without Losing Your Place
The word is pronounced so-RYE-ah-sis. That is it. The P at the beginning is silent. Most people who get this wrong are either reading the spelling and guessing based on how the word looks, or they have never actually heard it spoken aloud by a dermatologist or someone who deals with it regularly. Here is the breakdown if you want to nail it. So as in "socket." RY as in the start of "rye bread." AH as in "father." SIS as in the end of "oasis." So-rye-ah-sis. Three syllables, four distinct sounds. Some people will say "SIT-ee-OR-iss" and you will hear it occasionally in casual conversation. That version comes from misreading the Greek root. It sounds wrong to anyone who has had a conversation with a medical professional about this condition. You should avoid it unless you are talking to someone who does not care enough to correct you.
I ran into this exact issue years ago when I was writing patient education materials for a clinic. A copywriter had used "P-so-REE-ah-sis" in every headline because they were reading the word off a screen without consulting anyone. It made the whole document look unprofessional. I had to go through and replace it everywhere. Took about twenty minutes. The deeper problem is that English spelling is not a reliable guide for pronunciation, and psoriasis is one of the clearest examples of that. The silent P comes from the Greek word psora, meaning itch. The Greeks did not say the P in that context, and English inherited the silence when medical Latin brought the term into clinical use. If you want to internalize it rather than just memorize it, here is what works. Look up a video on YouTube of a board-certified dermatologist discussing psoriasis treatment. Listen to how they say it three or four times in the same video. Your brain will pick it up faster from context than from any phonetic breakdown. I did this myself because I could never remember where the stress landed until I heard it spoken naturally.
Another practical tip: if you are in a doctor's office and need to ask a question, just say it once out loud to yourself before you speak. So-rye-ah-sis. The second attempt will come out right. People tend to stumble on the first try because they are thinking about the spelling, not the sound. That hesitation is normal and nobody will judge you for it. There is a variation you might encounter where people say "so-RYE-a-sis" with a very light schwa sound on the middle vowel instead of a full AH. Both are acceptable in American English. The full AH version is slightly more common in clinical settings, but neither is wrong. Do not stress about which one to pick unless you are recording something formal. One counter-intuitive thing most people do not realize: the word psoriatic, which refers to the joint condition called psoriatic arthritis, follows the same pronunciation rules. So-RYE-at-ick. If you know psoriasis, you already know psoriatic. The same silent P, the same stress on the RYE syllable.

Where this breaks down is in highly regional accents. In some parts of the American South and in certain working-class speech patterns, you might hear the P pronounced or the stress shifted entirely. That does not make it incorrect in those contexts, but if you are aiming for standard American English, especially in a professional or medical setting, stick with so-RYE-ah-sis. If you need a quick reference, I keep a phonetic shortcut on my phone that just says "say it like 'sore eye a sis' mashed together." It sounds silly written down but it works as a mental anchor. I have used it with patients and coworkers when the word comes up unexpectedly and nobody wants to ask twice. Bottom line: silent P, stress on the second syllable, three beats total. So-rye-ah-sis. Practice it once out loud and you will stop second-guessing it.
