Learn English – Difference between “cross with you” and “angry with you”

Weltanschauung is used as an English word, from the German because the English worldview is too vague and not comprehensive enough. (For anschauen = to look at, rather with the meaning "to take a good look at", for schau = to show, display, as opposed to blicken = to look, or aussehen from sehen = to see).

Primarily it means a way a person looks at the phenomenon of life as a whole. Some people (particularly those who have not lived very long) have not formed any broad (inclusive, even "sophisticated") view of life. Others consider a large number of factors before forming their overall view — maybe in their seventies — of the phenomenon of human existence. Typically a person's Weltanschauung (as an English word we drop the capital letter required of all German nouns) would include a person's philosophic, moral, and religious conclusions — including e.g. the duality of spirit and matter — and perhaps their conclusions about the origins of the universe and of the development of life. They would also have conclusions about the state, society, politics and economic activity. I suggest def. "A person's conclusions about existence (however tentative) at a particular time of life, after taking a good look at everything they have come across about". What do the German philologists say about my amateur offering?

When you use the word group your emphasis should be on the collection of things in the group.

How many people do you have in your group?

When you use the word grouping your emphasis should be on the act of forming the group rather than the group itself.

Which grouping would be better- girls in one group and guys in another, or else adults vs children?
