I was browsing Tumblr and found this gem:
A cap(p)ella.
When spelling the name of the type of music, it is important to leave the double p there, so it’s an Italian phrase meaning “in the manner of the chapel”.
A capella, without the second p, is a Latin phrase meaning “away from the she-goat”. Probably not what you intended.

Spelling is important.
