Why don't I use this blatant impulse to fill the gaps in the internet, i.e. adding all music releases to artists, cover arts, learning about every genre, making a database, or add missing terms to Wiktionary, to study harder and fill up the gaps in my own knowledge instead? Why shouldn't I use this insatiable completeness hyperfixation to hone my own abilities?
gerund (noun-like) vs. true noun vs. present participle (adjective-like) vs. participial adjective
Any of various non-finite verb forms in various languages. In English, a "gerund" refers to a verb in its -ing form when used in a way that resembles the use of a noun. Despite showing noun-like behavior in the context of the surrounding sentence, gerunds show verbal behavior in the context of their own internal clause: they can take direct objects or be modified by adverbs. In this way, gerunds are distinguished from deverbal nouns ending in -ing, which occur in noun phrases that can take determiners or be modified by adjectives. For example, "manufacturing" is a gerund in the following sentence: "Efficiently manufacturing this device is difficult." It is a verbal noun (not a gerund) in this sentence: "The efficient manufacturing of this device is difficult." In other languages, gerund can refer to a form that often functions as an adverb to form adverbial phrases or the continuous tense.
When a participle functions as a noun, it is called a gerund. A participle may also function as an adjective (that is, a participial adjective), especially in attributive use. It can evolve to become either a true noun or a true adjective, or both, with a shift in meaning, sometimes substantial.
true noun: "The mapping of the city was a difficult task."
gerund: "Rapidly mapping the city was my best decision ever."
present participle / past participle: "I'm mapping the city right now." / "The sky darkened already."
participial adjective(s): "The mapping old man cries all night in the darkened sky."
