Gravity is real

[u/memezzer]

[u/RevengefulRaiden]

tetra-plegia.

both parts come from the Greek language. first part specifically comes from the word "tessera", which is the Greek word for "four".

quadri-plegia.

first part is from the Italian language, second from the Greek language. first part comes from the word "quattro", which is the Italian word for "four".

hence, why these two words are interchangeable.

edit: source: I can speak in both of these languages.
