pah-rah-plwee
Here's a breakdown:
* pah: The "pa" sound is similar to the "pa" in "path"
* rah: The "ra" sound is similar to the "ra" in "rat"
* plwee: The "plwee" sound is similar to the "play" in "play", but with a slight "ee" sound at the end.
Remember that the "u" in "parapluie" is silent, so it's not pronounced as a "u" sound.
