A lesson is a structured period of time where learning is intended to occur. It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor. A lesson may be either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time during which learners are taught about a particular subject or taught how to perform a particular activity. Lessons are generally taught in a classroom but may instead take place in a situated learningenvironment.
In a wider sense, a lesson is an insight gained by a learner into previously unfamiliar subject-matter. Such a lesson can be either planned or accidental, enjoyable or painful. The colloquial phrase "to teach someone a lesson", means to punish or scold a person for a mistake they have made in order to ensure that they do not make the same mistake again.
"Lessons" is the eighth episode of the first season of the HBO original series The Wire. The episode was written by David Simon from a story by David Simon and Ed Burns and was directed by Gloria Muzio. It originally aired on July 21, 2002.
One of Wallace's young charges wakes him for help with their math homework. Wallace appears unusually tired and irritable, but he awakes to assist with the child's school work anyway. The young kid is unable to do a simple story problem. Wallace asks a similar question, but uses the language of the drug business, instead of busses, which the kid solves in seconds. Poot shows up during the math lesson and encourages Wallace to come to work rather than lying around all day, which he has frequently been doing recently. He is reluctant and refuses to leave his room. He then asks to borrow money from Poot, who begrudgingly obliges. Afterward, Poot reports his concerns over Wallace's activities to D'Angelo, who wants to talk with Wallace face-to-face. Meanwhile, at the print shop (a Barksdale front), Stringer berates the staff for not acting like professionals.
South Koreans refer to themselves as Hanguk-in (Hangul:한국인;hanja:韓國人), or Hanguk-saram (Hangul:한국 사람), both of which mean "Korean country people." When referring to members of the Korean diaspora, Koreans often use the term Han-in (Hangul:한인;hanja:韓人; literally "Korean people").
Historical linguists classify Korean as a language isolate. The idea that Korean belongs to a putative Altaic language family has been generally discredited. The Korean language is agglutinative in its morphology and SOV in its syntax.
