~と思う: meaning, usage and examples
~と思う means: I think…
How to form it
<Verb / い-adj plain> + と思う / <Noun / な-adj> + だ + と思う; <Verb volitional> + と思う (intention)
Examples
明日は雨が降ると思います。
I think it will rain tomorrow.
彼はもう帰ったと思います。
I think he already went home.
この映画はとてもおもしろいと思います。
I think this movie is very interesting.
田中さんはもうすぐ来ると思います。
I think Mr. Tanaka will be here soon.
When to use it
と思う means "I think that". Use it to give your opinion or a guess about the future: この映画はおもしろいと思います. With the volitional form it shows a plan or intention: 来年日本に行こうと思います (I am thinking of going to Japan next year). It softens statements and is very common in polite conversation.
Nuance
と思う on its own is about the speaker's thought. For other people, use と思っている: 田中さんは無理だと思っています. Use と思っています for yourself too when the thought has continued for some time. Nouns and な-adjectives need だ before と.
Compare
と思う vs かもしれない: と思う gives your own opinion with some confidence; かもしれない only says something is possible. と思う vs でしょう: でしょう is a guess about facts and sounds more distant. ようと思う vs つもりだ: ようと思う is a plan you are considering; つもり is a firmer decision.
Tip: Do not forget だ with nouns and な-adjectives: 学生だと思います, 静かだと思います. Without it, the sentence sounds incomplete.
