A Japanese word "いろいろ" in English

いろいろ is very convenient to use in Japanese conversation.　

e.g) 私は先週末、いろいろな場所へ行きました( I went to many places last weekend. )
　　この道具は、いろいろな用途に使えます( This tool can be used in various ways.)
　　最近いろいろと悩んでしまいます( I'm I have been worried about some things recently.)
What kind of words or phrases can I substitute for いろいろ？
Please tell me if my e.g. sentences are not natural.

Thank you.

Hello Saki,

Your sentences are fine, good job!

Because you used "recently" for the last sentence, "I have been" indicates that this sense of worry has been going on for some time and would thus be more suitable.

If you want to use "I'm", then the sentence, "I'm worried about some things." would be better. Although this second sentence could also show that you've been worried for some time, it emphasizes more on the present – that you are worried now/at this point in time.

And because using いろいろ indicates many/diverse/various things, we would use the plural forms instead of the singular forms. As seen above, the plural forms: "places", "ways", "things" would then be used.

Depending on the context of your sentence, there are quite a number of English words that can be used to substitute いろいろ. You've used some yourself in the examples above – many and various.

Other similar words include: assorted, several, numerous, various, diverse etc. 

E.g.

1. 部屋にはいろいろなものがあった。

There were various/a number of things/articles in the room.

Also, instead of using one word to substitute いろいろ, you could make use of the sentence structure instead.

2. 彼は私にいろいろと親切にしてくれた。

He has shown me much kindness. (OR: I have been on the receiving end of his many acts of kindness.)

3. 彼女の話はいろいろなところへ飛ぶ。

She frequently jumps from one topic to another when she is talking. 

I hope this make things a little clearer. I'm a beginner in Japanese so I'm not 100% sure that the examples are grammatically correct in Japanese. Do tell me if they're wrong! Thank you very much.

Update 2:

"Recently" (or "lately") and "最近" are exactly the same meaning wise. "Recently" does not exactly indicate just the past but more like a period of time from the past until now. 

E.g.

Past----------------Present----------------Future

        <---Recently--->

Hi Raúl, "I began to learn English..." isn't a complete sentence and is actually a little unnatural in its structure. You should continue the sentence with when you actually started learning English. "I began learning English (when I was)..." or "I started learning English (when I was)..." would be better ways of structuring the sentence. E.g. I started learning English when I was in the University. I started learning English at a summer camp in school. Update 1: As Angela has mentioned, "I began to learn English" or "I began learning English" can be complete sentences as well. However, since you've asked about how you could use these sentences, I would say that adding a little context to these stand-alone sentences would make them more 'complete'. For example, the above would be perfectly fine as a sentence if it were a reply to a question: A: What did you do during your summer holidays? B: I began learning English. Update 2: Vivian's reply below works as well! Hope this makes sense! All the best in learning English!

Short formal letter

Dear Sir/Madam
I'm writing to enquire about whether you have found my player which I forget in the player that I had accidentally left in your classroom when had studied on your language course at last week during last week's language course.

I'm almost certain that I had left it in the classroom number five. I do hope it has been found. It is a black Sony compact player with red headphones.

I would be grateful if you could return it when I'm going to visit your the city at next week.

Yours faithfully.
Dmitry Rusanov.

I just shifted some words around and simplified sentences to make it flow better:)

A tour with a friend of my wife's in Thailand

Last Saturday and Sunday  weekend, my wife's friend came to Thailand . So we went to on a tour.
On Saturday, we went to the Chatuchak weekend market. There were many many shops about selling clothes, accessories, bags etc... And There were many people/tourists visited there at the market. (Or you could say: The market was very crowded.)
We enjoyed shopping together. 

On Sunday, we went to Kanchanaburi because we wanted to see an old railway. We saw the a railway made that was built at in World War 2. The railway was near by a mountain. I think it is must have been difficult to make build it.

The Our/My wife's friend enjoyed her stay in Thailand, so I'm happy (Or you could say: and that made me happy).

I hope that helped! Keep it up!

Hello there! These two phrase may sound the same but are in actual fact very different in application. "I couldn't care less" is negative in its connotations and is applied in situations (as you've mentioned) where people are not at all interested in the situation at hand. E.g. A: Did you hear about Jane failing all of her exams? B: Jane? I couldn't care less about her. She used to bully me in middle school. "I could care less" is almost never used and is rather a misuse of the "I couldn't care less". You could probably use it in this way but do note that it is very unnatural: A: You're not obligated to help Jane, you know. Don't let it affect your grades. B: I (wish) I could care less but she's my friend. In short, "I couldn't care less" means that you have absolutely no interest in a situation and thus have no more "care" to give. Whereas, "I could care less" means that you still care but could/should probably not "care" as much, and this phrase is almost never used.
