gerund

A verbal form that functions as a verbal noun. (In English, a gerund has the same spelling as a present participle, but functions differently; however, this distinction may be ambiguous or unclear and so is no longer made in some modern texts such as A Comprehensive Grammar of the English Language and The Cambridge Grammar of the English Language)

由动词构成的名词(如英语动词的-ing形式用作名词)

a noun formed from a verb (such as the `-ing' form of an English verb when used as a noun)

In some languages such as Dutch, Italian or Russian, a verbal form similar to a present participle, but functioning as an adverb to form adverbial phrases or continuous tense. These constructions have various names besides gerund, depending on the language, such as conjunctive participles, active participles, adverbial participles, transgressives, etc.
