What does lesson mean?
A lesson is a period of teaching or a unit of instruction, such as a class in music, language, or history. The word can also refer to something learned through teaching or experience: a difficult experience may teach us an important lesson. In this second sense, lessons often have a cautionary or morally instructive quality, as in "learn a lesson" or "a lesson in patience." A lesson can additionally mean a warning or example intended to correct behavior. The word is common in education, personal development, and figurative discussion. Although its basic sense concerns instruction, it is also used for the lasting insight that an event may provide. The verb "to lesson" exists, but it is relatively uncommon and sounds formal or literary compared with the well-established noun.
A period of instruction or teaching, especially one intended to teach a particular skill or subject; also, knowledge or an important principle gained through teaching or experience.
"The course is divided into ten weekly lessons."
The word may also denote an instructive example, warning, or moral, often with the sense that an experience has revealed how something should be done or avoided.
To teach or instruct someone, especially by conveying an instructive example or warning.
"The incident lessons even experienced drivers to leave a greater following distance."
This use is less common than the noun and has a formal or literary tone.
The standard plural form is used for separate periods of instruction or for multiple principles or examples learned through teaching or experience.
"The pupils learned several valuable lessons from the project."
The word lesson began with the idea of reading: its Latin ancestor meant a reading, and the word still carries the sense of something worth learning.

Etymology of lesson
The word comes through Anglo-French and Old French forms from Latin "lectionem," a noun derived from the verb "legere," meaning "to read" or "to gather." In English, its meaning developed from the idea of a reading or text to be learned into the modern senses of a period of teaching and an instructive principle or example. Its relatives include "lecture," "legible," and "legend," all of which are associated with the same Latin root.
