In grammar, if you use a verb intransitively, the verb has a subject but no object.

In grammar在文法上, if you use a verb intransitively如果你不及物地使用一個動詞, the verb這個動詞 has a subject but no object有主詞但沒有受詞。

In “They arrived,” arrived is used intransitively: we do not arrive something. In “She laughed,” laughed is the same kind of use. Many verbs can go both ways: “He eats” (intransitively — we are not told what) versus “He eats rice” (with an object).

In "They arrived,"在「They arrived」這句裡, arrived arrived is used intransitively是不及物地被使用的: we我們 do not arrive something不會說「arrive某個東西」。In "She laughed,"在「She laughed」裡, laughed laughed is the same kind of use是同一種用法。Many verbs很多動詞 can go both ways兩種用法都可以: "He eats"「He eats」 (intransitively不及物地——we are not told what我們不知道吃了什麼) versus跟 "He eats rice"「He eats rice」相對 (with an object有受詞)。

Learner dictionaries mark intransitive verbs [I]. This adverb lives almost only in language class and grammar notes; you will rarely need it in ordinary talk.

Though actually, “intransitive” here is only a grammar label. It does not mean “not moving from place to place,” and it has nothing to do with public transport.

Though actually不過其實, "intransitive" here這裡的「intransitive」 is only a grammar label只是一個文法標籤。It它 does not mean "not moving from place to place,"不是指「不會從一個地方移動到另一個地方」, and而且 it has nothing to do with public transport跟大眾運輸一點關係都沒有。
