Szia Yair! Important: Don't use "lecke" for a lesson (like having a lesson in school or with a private/online teacher)! Many students make that mistake but it's wrong. Lecke has three basic meanings: 1. Tanórán feladott feladat (homework given by a teacher in a lesson/class, so "lecke" means homework informally) Példa: A tanár sok leckét (házi feladatot) adott fel megint. (The teacher gave lots of homework again) 2. Tanulság (moral, something you learn from some experience). Példa: Ez jó kis lecke volt neki! (That was a good lesson for him - "He learned a lot from that, next time he won't make the same mistake!") 3. lecke = unit in a textbook Unit 5 = 5. (ötödik) lecke So, if you want to say "lesson", use "óra" instead of "lecke"! Példák: Hány órád van ma? Hat. (How many lessons/classes do you have today (in school). Six.) 8-kor lesz egy online órám. (I'll have an online lesson at 8). Ma nem volt németórám, csak angolórám. (I didn't have German lessons today, only English lessons.) 2. KÉRDÉS elcserél/kicserél elcserél - 1. you exchange sth with sb. on purpose 2. you swap sth with sth else by accident Példa: Elcseréltem Péterrel a telefonomat. ( I gave my phone to Peter and he gave me his phone for good) Elcseréltem a könyvemet egy telefonra. (I exchanged my book for a phone - I got a phone in return for my book) 2. Elcserélték a kabátunkat a színházban. (in the theatre our jackets were swapped by mistake) Kicserél - 1. újat, jobban használ valami helyett (use sth new or better instead of an old thing) 2. replace a faulty item in a shop 1. Kicseréltük a régi szőnyeget. (We changed the old carpet for a new one) 2. Kicserélték a rossz telefont (=kaptunk egy másikat, egy jót helyette) The faulty phone was replaced (and we got a good one for it in the shop) These differences by prefixes are often very difficult to understand and so they are mostly topic for advanced students. Remélem, ez segít! :) Krisztina
