How Do You Spell PTARMUS?
Pronunciation: [tˈɑːməs] (IPA) 
The word "ptarmus" is a tricky one to spell. It is pronounced /ˈtɑːməs/ and is derived from a Greek word meaning "to sneeze." The unusual spelling is due to the silent "p." The letter "p" is originally from the Greek language and is used to represent the aspirated sound /pʰ/. In English, however, the letter "p" is often silent when it appears before the letters "t" or "s." So, in "ptarmus," the "p" is silent, and the word is pronounced as "tarmus."
