かばって英語でなんて言うの？

「カバ」の正しい英語の言い方は「hippopotamus」（発音：ヒポポタマス）ですが、会話で「hippo」(発音：ヒポー）という省略を使います。

This little guy, I say little I mean big, has two names. The proper one, I suppose, is hippopotamus. But we like to shorten it to Hippo, it is easier.

And origins of the name are as follows:
Middle English: via Latin from Greek hippopotamos, earlier hippos ho potamios ‘river horse’ (from hippos ‘horse’, potamos ‘river’).
