How Do You Spell BALLPROOF?
Pronunciation: [bˈɔːlpɹuːf] (IPA) 
The word "Ballproof" is often misspelled as "Bulletproof" because of their similar meanings. However, the correct spelling is with two L's: "Ball-proof". The IPA phonetic transcription for this word is /bɔːl-pruːf/, with the stress on the first syllable. The word "ball" refers to the spherical shape, while "proof" means something is resistant to damage or harm. "Ball-proof" therefore indicates something that can withstand impact from a ball, such as a protective shield or material.
