There are many other terms and expressions and relating to "way" for example, sidetrack, out of the way, roundabout way of speaking, etc. Where did the term by the way come from? I've googled it, to no avail, and may be its because it's been coined in a book or something. Does anyone know anything relating to this saying? And maybe explain the popularity of terms relating to "way".

Your question is conflating two different meanings of "way".

"By the way" is literally "by the side of the road", but the OED cites its figurative use ("Incidentally, in passing, as a side-topic.") from 1556. I don't believe a single authoritative source will ever be identified for it, as I guess it was in common speech before 1556.

"Sidetrack" uses the same metaphor, as you imply.

But "roundabout way of speaking" is "roundabout [way of speaking]", and uses "way" in the sense of "Manner in which something is done or takes place; method of performing an action or operation." (the OED's sense 14 a).


The Corpus of Historical American English has examples of sentences containing by the way from 1810 and later years.

That, Sir, is the type, symbol, and adopted emblem of our nation, the BALD EAGLE, who, by the way, is not bald, any more than that stout and sturdy youth, the thriving republic, whose character he represents; only his head and neck are white; so is his tail; the rest of his body is brown. —North American Review: March 1818: 405-409.

It is also used in the following sentences:

But faith I must be off, or day-light will overtake me by the way: Oh good by my poor dear, dead girl, I suppose your ghost will be after following me over the country, and never cease crying, Dermot, you kilt me. exit.—M. (Mary) Clark, The Fair Americans (1815).

He comes by the way of the fields, creeping through hedges, leaping ditches, and looking around him with all the apprehension of a felon that has just broke jail.—William Dunlap, The Italian Father (1810).


"Then fairly I bespoke the officer To go in person with me to my house. By the way we met My wife, her sister, and a rabble more of vile confederates;"

The Comedy of Errors, William Shakespeare ACT V scene i, lines 233-237

This was written sometimes in the 1590's.


While reading Maya Angelou's "I Know Why the Caged Bird Sings", I learned that "the way" portion refers to God as in "the way, the truth and the light"; so by the way would mean literally "By God".

    Are you trying to claim that “by the way” has some sort of Biblical meaning? Extraördinary claims demand extraördinary evidence — as do I.

    Maya’s grandmother believes by the way to be a minced oath meaning “by God” or “by Jesus”, but this opinion is contradicted by the history of the expression, according to Word Detective.

    @tchrist Gary was merely mentioning that Maya Angelou was spanked ferociously for saying "by the way" when talking to her brother. Maya was confused as to why she was being beaten for something so trivial, until her grandmother told her that evening that the way is God and saying "by the way" is the same as saying by God or by Jesus which is considered cursing. No evidence needed: just an African American's interpretation from the late 1930's. I'm sure this interpretation resonated in many poor black communities in those times.

    @user78045 that is an extraordinarily generous interpretation of Gary's answer, but I do appreciate you adding some historical context to it.
