Noun form in Engpsh refers to the way a word is used to name a person, place, thing, or idea.
It originates from Latin, where nouns were classified into several forms based on their use in sentences, such as proper nouns (e.g. John, London), common nouns (e.g. man, city), and collective nouns (e.g. team, flock).
Examples in Engpsh with Chinese translation:
Proper noun: "John" 约翰
Common noun: "book" 书
Collective noun: "class" 班级
In a sentence:
John is a doctor. (约翰是医生。)
She bought a new book. (她买了一本新书。)
The whole class went on a field trip. (整个班级去了野外旅行。)
