SIN-uh-pseez
Here's a breakdown:
* SIN: The first syllable is pronounced like the word "sin."
* uh: The second syllable is a short "uh" sound, like the "u" in "up."
* pseez: The final syllable is pronounced like "peace" but with a short "ee" sound.
It's important to note that the "s" at the end of "synopses" is pronounced, making it sound like a plural word.
