Frequently Asked Questions

Do "Iga" and "is" mean the same thing in a sentence?
No - they are not even the same part of speech. "Iga" is a name and "is" a verb, so a sentence built for one is usually ungrammatical with the other.
In ordinary English text, does "Iga" or "is" show up more?
"is" is the more common of the two: it sits at frequency rank #8 in our English list, against #37,503 for "Iga". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
