I don’t understand this one lesson, actually I don’t understand this whole grammar point. I’m going through Genki and Tae kim along with bunpro for extra help. But my dumb brain is just not getting this. Please help


It’s like if you’re saying "the hot one, the cold one, the blue one.

Which sweater do you want?

(The blue one)

The sentence above literally says “I also like the hot one”, which I guess is translated as “of the two options for air that I can choose from, I like the hot one”.


That makes sense, thanks.
I think the example sentences are what throws me off.


Hey :blush:

Which part was problematic, I want to improve the grammar point with more sentence explanations but need your feedback.
I will also try to explain everything you don’t understand in a simple (and detailed) way :bowing_man:

I love the avatar. Is nickname inspired by a song, maybe?

I understand the grammar point now. I think what is confusing to me about the sentences is that I don’t understand the ‘hidden’ context. So then I’m trying to figure out what の is replacing.
So with this sentence: 「暑いのも好きだから、エアコンがなくてもいい。」there is a previous conversation about weather maybe and then the above is the response, so のも is replacing weather.

Maybe if what の is replacing was put in brackets or highlighted yellow, that might make it a bit easier or a least for me it would.

I don’t know why I’m having a hard time with this point, on other points I get it the first time.

I can’t remember where I found the picture but I use it for everyting now, it’s so かわいい.
Yup my mom liked the name of the song so much she named me after it (The guy who sang it is Marillion).


Got it! We will try improving it according to the suggestion!


I love that song too, say hi to your mom :+1:


To add to this, maybe some type of “stepping-stone translations” could be added for unintuitive example sentences of certain grammar points.

This could be a literal translation of an example sentence if that sentence is unintuitively constructed in to an English-speaking person.

An example would be my explanation in post #3.

I like the idea!
I thought about something similar.

So this sentence came up as part of the N5 review section (see image attached). It’s specifically a review sentence from N5 Lesson 8: 11/13, the の particle. I’m really having a difficult part dissecting this sentence though. Can someone help me?

From what I understand, this lesson is trying to teach の as an indefinite pronoun meaning ‘one’. In this way 白の would be ‘white one’.

I think I’m struggling with what こと means in this sentence. 心配 is ‘worry’, 彼のことだ is something like ‘it is his thing’. Assuming こと translates as ‘thing’ and not as some grammatical structure I am unfamiliar with. Can someone help me piece this together? I just don’t get how you can get from ‘the one that worries, it is his thing thing’ to ‘the one that I am worried about is him’. My brain reads it more like the first than the latter.

When talking about feelings for someone, it’s common to talk about the “idea of” or the “whole of” that person.
こと = thing or idea
彼のこと = the idea of him
彼のことが大好きだ = I love him (I love the idea of him)

心配なのは = the worried thing, the thing that worry is applied to, the one that I’m worried about
心配なのは 彼のことだ = The one that I am worried about is him.
:warning: the person that worries = 心配する人は


That helps a lot, thanks! Your example was great.
