infinitive
Grammatical term for the base form of a verb, often used with 'to' in English. In Japanese grammar, it may refer to the dictionary form or specific non-finite forms.
English infinitives have nominal, adjectival, and adverbial uses.
「to go」は不定詞の一例です。
'To go' is an example of an infinitive.
原形 means 'base form' or 'dictionary form', which is related but not always identical to the infinitive concept in English grammar.
to-infinitive; full infinitive
split infinitive
bare infinitive; root infinitive
Compound of 不定 (indefinite) and 詞 (word/part of speech), likely a calque from Western grammatical terminology.
