What is the most common mistake people make when pronouncing this term?
+
The biggest mistake is stressing the wrong syllables. Many people say 'ack-KWYRD' or put stress in the middle of 'immunodeficiency,' but the correct stress is on the first syllable: AH-kwyerd ih-MYOO-noh-deh-FISH-en-see. It helps to remember that each main word in the phrase has its own stress.
How many syllables does 'Acquired Immunodeficiency Syndrome' have?

The full term has 13 syllables when broken down: Ac-quired (2) Im-mu-no-de-fi-cien-cy (7) Syn-drome (2). That's why the abbreviation AIDS is so much easier to use in everyday conversation!
What does the root 'immuno' come from?

'Immuno' comes from the Latin word 'immunis,' which relates to protection or resistance. You'll see this root in other medical words like 'immunity,' 'immunology,' and 'immunization'—they all deal with how the body protects itself.
