whats it called when you say (for example) marker of books instead of bookmarker?

Question

FOR EXAMPLE!!!! i don't care about BOOKMARKS!! the context is IRRELEVENT give me better answers. now.

Answer 1

book marker is a compound noun, an endocentric compound, consisting of a head, i.e. the categorical part that contains the basic meaning of the whole compound, and modifiers, which restrict this meaning. For example, the English compound doghouse, where house is the head and dog is the modifier, is understood as a house intended for a dog. Endocentric compounds tend to be of the same part of speech (word class) as their head, as in the case of doghouse. In English, the head of a compound word is the last morpheme (that is, the smallest linguistic unit that has semantic meaning).: bookmark, mark is the head, book limits the kind of mark.

Answer 2

Context, a marker of books could be a teacher marking your homework, however, a bookmark is used to ensure you don't lose your place in the book you are reading or referencing.
It is important to always work out the context of what you are writing or saying. It can be misinterpreted to mean a complete opposite.

Answer 3

A marker of books could be a child scribbling with a crayon. Things can be taken out of context. I usually just say "Bookmark."

Answer 4

When you say, "Mistakes were made" instead of "We made mistakes", it is called writing in the passive voice. This sound very similar.
