intransitive verb

transitive adj.(grammar)(of a verb) taking a direct object.
eg:-This camp is for the use of persons (eg.refugees, soldiers,)

intransitive adj (grammar)(of a verb/verbs)used without a direct object.
Intransitive verbs, verbs having incomplete meanings and special finites do not appear in the passive form. Note that there are some exceptions !----------------
Only transitive verbs or transitive phrasal verbs can be changed into the passive.Note that they are taking direct objects.(as mentioned)
eg:-In the implied passive in gerund and infinitives:-
eg:-Your buttoned trousers need mending.
eg:-This load is too heavy.
eg:-This paragraph is too easy.
eg:-A lie was told.
eg:-I was trusted.
eg:-The thief was seen.
eg:-The prize was given.
eg:-The sun also rises !

Some explanations:-it is used without a direct object.The verb "die" as in sentence"He died suddenly", has the meaning of intransitive. Intransitively adverb:-eg:-The verb is being used intransitively ! eg:-"die" as in "He died suddently"THX.

Intransitive verb (不及物動詞)

不及物動詞不能有 object (賓語)
不能有 passive voice (被動式), 事因無賓語

不及物動詞例子 sleep, arrive, lie, swim, happen, …etc.)

subject (主語) + intransitive verb [ + adverb or prepositional phrase]
They sleep.
He has arrived.

They slept badly
He arrived early.
(badly. 與early 是 adverbs)

They slept on the beach.
(“on the beach” 是 prepositional phrase)

言及 intransitive verb, 要講 transitive verb.

Transitive verb (及物動詞)
及物動詞有 object (賓語)
大多數可以轉去 passive voice

subject (主語) + transitive verb (及物動詞) + object ((賓語)

Peter murdered David.

"murdered" 是及物動詞
“Peter” 是 subject; “David” 是 object
這是 active voice (主動式)
轉去被動式
David was murdered by Peter.

被動式有時無 agent
David was murdered. (不知道 agent是誰)

Peter was arrested (by police).
“by police” 很多時被刪除, agent 明顯地是 police)

許多的 verbs 可以 transitive 和 intransitive
不是兩者隨意都得, 可以有或無 object, 要看動詞性質改變和意思
I open the door. (open 是及物動詞)
Many shops open early. (open 是不及物動詞)

題外:
transitive verb 和 intransitive verb 屬于action verb (dynamic verb)
另外一種 state verb (static verb) 狀態動詞, 使用 linking verb
最簡單的句子形式
Subject + be + adjective/noun(or noun phrase)
(be 是 linking verb, be 可以是 am, is, are, was, were, will be ….)

She is beautiful.
因為這句是無 object, “is” 可以做 intransitive verb, 這想法是嚴重的錯誤
在這句, “is” 是 linking verb, 表示狀態, 不是 intransitive verb

"eg:-This load is too heavy.
eg:-This paragraph is too easy."

TOMING88 can't tell the difference between linking verb and intransitive verb/transitive verb.
Try your best 不要寫錯

intransitive adj = intansitive adjective ?
應用 bracket, intransitive (adj ) or put "adj" in italic.
