Frequently Asked Questions

Do "beg" and "by" mean the same thing in a sentence?

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

Which is more common, "beg" or "by"?

"by" is the more common of the two: it sits at frequency rank #24 in our English list, against #6,544 for "beg". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
