 1. To gain knowledge or information of; to ascertain by inquiry, study, or investigation; to receive instruction concerning; to fix in the mind; to acquire understanding of, or skill; as, to learn the way; to learn a lesson; to learn dancing; to learn to skate; to learn the violin; to learn the truth about something. “Learn to do well.”

 2. To communicate knowledge to; to teach. [Obs.]

 To make perfumes ?   --Shak.
 Note: ☞ Learn formerly had also the sense of teach, in accordance with the analogy of the French and other languages, and hence we find it with this sense in Shakespeare, Spenser, and other old writers.  This usage has now passed away.  To learn is to receive instruction, and to teach is to give instruction.  He who is taught learns, not he who teaches.
