Doing in English is a verb or a noun A gerund is a verb or a noun

There are two kinds of doing: present participle and gerund.

Now the participle is a verb and can be used as a predicate along with the verb be; If it is not used in conjunction with the verb be, it cannot be used as a predicate, but only as an adverbial, a definite, and a complement.

A gerund is a noun and can only be a subject, object, or definite.

Such as: i'm thinking.(Present participle, with be a predicate).

Speaking of the word dong alone, it is a noun. There are many meanings, you can look up the dictionary yourself. For example: I never heard of such doingsI've never heard of any of these things.

But I think you're asking about the -ing participle form of the verb do, e.g., the teacher looks at her students donging their homeworkThe teacher was watching her students doing their homework.

The -ing participle form of the verb do is made up of the gerund and the present participle, both of them are in exactly the same form, both of them are formed by the verb primitive form plus -ing. Since they are derived from verbs, they still have the nature and original meaning of verbs, but they cannot be used as verbs. Specific to your question, since gerunds are changed from verbs, they naturally still belong to the category of verbs, but it should be remembered that the functions and usage of gerunds are different from verb prototypes, and they have some functions of nouns, which can be used as nouns in sentences, as subjects, objects, predicates, and adjectives.

It can also be modified by an adverb or dominate the object. That's why you can't figure out whether a gerund is a verb or a noun.

In the last sentence, gerunds belong to the range of verbs, and the nature counts as verbs.

The properties of both are possessed, which belong to non-predicates, and can be done in sentences in addition to predicates, such as: subject, object, predicate, adverbial, complement, and definite.
