Usage Guide
Can learn mean teach?:
Learn in the sense of "teach" dates from the 13th century
and was standard until at least the early 19th.
made them drunk with true Hollands
—and then learned them the art of making bargains
— Washington Irving
But by Mark Twain's time it was receding
to a speech form associated chiefly with the less educated.
never done nothing for three months
but set in his back yard and learn that frog to jump
— Mark Twain
The present-day status of learn has not risen.
This use persists in speech,
but in writing it appears mainly in the representation of
such speech or its deliberate imitation for effect.

Usage Notes
'Teach 'em' or 'Learn 'em'?
When did 'learn' stop meaning "to teach?"
What to Know
We do offer a definition of “teach” for learn,
although it is labeled nonstandard and
tends to be used in an intentionally informal manner.
The English language can be quite fickle.
Some words
(such as flingee, “the person at whom something is flung”)
slide out of fashion in entirety, leaving behind nothing but a record in old books or current ones (such as dictionaries)
which pay attention to old words.
Some words remain in common parlance,
but have left behind their initial meanings
to such an extent that they are now essentially lost;
absurdity once referred to dissonancein music,
but now is most commonly found
meaning “something that is absurd.”
And then there are certain other words
which have meanings
that floatsomewhere in between current and lost,
such as the sense of learn meaning “to teach.”
Once upon a time it was entirely normal
to use learn with the meaning of
“to teach,” or “to inform of something.”
All the cool writers did it:
William Shakespeare, Noah Webster, Goffe Thomas
(we are stretching the boundaries of
what might be considered
a cool writer just a touch).
From the 13th through the end of the 18th century
the use of learn to mean “teach” was fairly common,
although the 1785 edition of Samuel Johnson’s dictionary
(the 6th edition) labeled it as obsolete.
And while Noah Webster used it in his letter writing that year,
by the time he published his dictionary in 1828
this sense of the word had either taken a turn for the worse,
or someone had teased him about using it thusly,
as he seems to have changed his mind about it.
Webster did define learn as
“to teach, to communicate
the knowledge of something before unknown,”
but included a note at the end of the entry,
“this use of learn is found in respectable writers,
but is now deemed inelegant as well asimproper.”
Although this use may very wellhave been viewed
as inelegant and improper, it has not died away.
We still see learn used to mean “teach”
in common use throughout the 19th and 20th centuries,
although it tends to be employed in an intentionally colloquial manner,
signifying informal speech or lack of formal register.
We do offer a definition of “teach” for learn,
although it is labeled nonstandard,
and you may wish to avoidsuch use
unless a specific effect is intended.
It is interesting to see
how a word’s meaning may take on a sort of half-life,
wherein it is perhaps kept alive largely by writers
who are intentionally using it
in a linguistic register that is not entirely their own.
As any discussion on this subject
should make mention of what is probably
the most well-known and beloved passage of literature
containing an explication of the difference
between teaching ‘em and learning ‘em,
here is Kenneth Grahame’s explanation from the early 20th century.
