How to pronounce “itis” in words about inflammation

The meaning and origins of “itis”

Do you find it hard to pronounce words that end in “itis”? It’s found in many medical words so the right pronunciation is important. First of all, let’s look at what it means. The suffix “itis” comes from Latin and Greek and means inflammation or a disease characterised by inflammation.[i] It is usually attached to a word root that signifies a part of the body and means that this body part is inflamed. Sometimes it is an acute condition like laryngitis and other times a more chronic condition like hepatitis. One of the earliest uses of this suffix in English was arthritis as early as the 1500s and meaning inflammation of the joints.[ii]

Tip 1 – There are two different “i” sounds

One of the reasons some have trouble pronouncing the suffix “itis” is that each “i” has a different sound. English has 12 different vowel sounds and Spanish 5, for example. As a result, for Spanish speakers, the suffix “itis” is often mispronounced because they pronounce each “i” the same and in the way they pronounce this letter in Spanish (like ee or arth-ree-tees).

In English, this suffix is in two parts “i” and “tis”. The first “i” has a long vowel sound which means it sounds like the name of the letter.


The second “i” has a short vowel sound (like the “i” in “sit”)


Tip 2 – The stress is on the first “i”

In addition to the two vowel sounds, the accent or stress in the word occurs in the part of the word that is pronounced with the first “i”. For example, let’s take the word gastritis.

It has three syllables:

Ga-stri-tis           Ga-stray-tis (phonetically)

You can see that I wrote the first “i” sound combined with the consonant sound that occurs just before and it is this combined sound that carries the accent.

That’s it!

Author’s note:

Dictionary.com is a site I like to use because it has many medical terms and they use phonetic spelling in addition to the phonetic symbols (and audio clips) to show how to pronounce words. I use phonetic spelling, not the phonetic symbols in my posts to make it easier for those not familiar with the international phonetic symbols.
