How to Pronounce St. Louis Encephalitis

It's pronounced SAYNT LOO-is en-sef-ah-LY-tis. Start with "saint" (like the word for a holy person), then "loo-ee" (rhymes with "gooey"), then break the second word into chunks: en-sef-ah-LY-tis, with the stress on the "LY" part.

The stress falls on the third syllable from the end: en-sef-ah-LY-tis. A common mistake is stressing the first syllable (EN-sef-ah-lit-is), but the correct way emphasizes the "LY" sound.

Saint Louis En-ceph-a-li-tis breaks down as: SAYNT / LOO-is / en / SEF / ah / LY / tis. The first part (Saint Louis) names a place, and the second part (encephalitis) is the medical condition.

Encephalitis means inflammation of the brain. The word comes from Greek: "encephalo" means brain, and "-itis" means inflammation or swelling.

The disease was named St. Louis Encephalitis because a major outbreak happened in St. Louis, Missouri, in 1933. Medical conditions are often named after the places where they were first identified or studied.

Encephalitis comes from two Greek parts: "encephalo-" (en = in, kephale = head/brain) and "-itis" (inflammation). So the word literally means "inflammation in the brain."

The short form is SLE, pronounced by saying each letter: S-L-E. This abbreviation is commonly used in medical writing and conversation to save time.

Many medical words use "-itis" to show inflammation: meningitis (inflammation of membranes around the brain), arthritis (inflammation of joints), and bronchitis (inflammation of airways). Once you know "-itis" means inflammation, you can understand these related words more easily.
