I am confused, which differences between are: Requirement, demand, need, demand?
I'm sorry..I don't speak German but I can answer in English
REQUIREMENT. Sometimes when you go for a job..the requirement for the job is that you need to speak English, or the requirement for the job is that you can type.
DEMAND. Demand is to ask for something, but you are not actually asking. You are demanding. GET ME THAT BOOK! GET YOUR HOMEWORK DONE! you are demanding. You are not asking them. You are telling them.
NEED...is when you actually need something. You are poor, so you NEED money to be able to buy food. A NEED has to be met. To be able to buy a house, you NEED to have money.
However, a need can also be a requirement. Its just a different word. You can also say you REQUIRE money to buy a house, because you NEED to have a house for your children.
Hope this helps.
