Frequently Asked Questions

Can "ide" and "is" be used interchangeably?

No - they are not even the same part of speech. "ide" is a noun and "is" a verb, so a sentence built for one is usually ungrammatical with the other.

In ordinary English text, does "ide" or "is" show up more?

"is" is the more common of the two: it sits at frequency rank #8 in our English list, against #24,195 for "ide". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
