How to Pronounce Sexually Transmitted Infection

Say it like this: SEK-shoo-ah-lee trans-MIT-ed in-FEK-shun. Break it into three main parts: "sexually" (SEK-shoo-ah-lee), "transmitted" (trans-MIT-ed), and "infection" (in-FEK-shun). The stress falls on the first syllable of each word: SEK, trans, and in.

The word has three stressed syllables, one in each part: SEK (in sexually), trans (in transmitted), and in (in infection). A common mistake is stressing the wrong part—like saying sex-shoo-AH-lee instead of SEK-shoo-ah-lee. Remember to emphasize the first syllable of each of the three main words.

It means something that spreads from one person to another mainly through sexual contact. "Sexually" refers to sexual activity, and "transmitted" means passed from one person to another, like how a cold can spread from person to person.

The abbreviation is STI, which you pronounce by saying each letter: S-T-I. Some older sources use the term STD (sexually transmitted disease), but STI is more common in modern medical language. Both abbreviations mean the same thing.

The prefix "trans" comes from Latin and means "across" or "through." The root "mit" (from Latin mittere) means "to send." So "transmitted" literally means "sent across or through," which makes sense when describing how an infection passes from one person to another.

Words like "transmission" (the act of passing something along) and "admission" (being sent into a hospital) share the same Latin root. You'll also see it in "emit" (to send out) and "remit" (to send back). All these words connect to the idea of sending or passing something.

You might hear it in a sentence like, "The doctor explained that using protection can reduce the risk of sexually transmitted infection." The term is used as a formal way to describe any infection that spreads through sexual contact.

An "infection" is when germs enter the body, while a "disease" is the illness that results. The term STI is more accurate because it focuses on the infection itself, regardless of whether symptoms appear. This is why STI has become the preferred term in modern medical language.
