JLPT N2

～からなる

Consist of; be composed of

Structure

Noun + からなる

This grammar point is used to state what something is made up of or how it is composed, describing its constituent parts.

このグループは５人のメンバーからなる。

This group consists of five members.

Using it for materials something is made *out of* (e.g., 木から作られている); it's for components or members.

Think of から (from) plus なる (to become); 'it becomes from' its components, thus 'it consists of'.

Import an article and tap any sentence using it. The explanation comes back about the sentence in front of you, not a textbook example.
