Frequently Asked Questions

Do "for" and "Form" mean the same thing in a sentence?

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

In ordinary Portuguese text, does "for" or "Form" show up more?

"for" is the more common of the two: it sits at frequency rank #220 in our Portuguese list, against #18,599 for "Form". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
