が・ のの in place of が, before a noun
Inside a description that comes before a noun, が can turn into の: 私の作った料理 is 私が作った料理, "the food I made". You will meet it everywhere and never have to use it, because が is always right.
We all ate the cake my mother made.
I want to live in a house with a big garden.
How to form it
Noun + が/の + verb or adjective + noun
Only inside a description of a noun.
The same meaning
The photographs he took are on display.
What you learned first.
The photographs he took are on display.
The same thing. の marks who took them.
Reading it: が, or plain の?
When の is followed by a verb or an adjective and then a noun, try が in its place. If the sentence still makes sense, this の is が. If it doesn't, it is the ordinary の.
This is a bag my older sister made.
姉が作った, "my sister made it", makes sense. This の is が.
This is my older sister's new bag.
姉が新しい, "my sister is new", doesn't. The bag is new, and の is plain "'s".
Where you'll meet it
Most of all in short descriptions of what someone or something is like, and in phrases people say every day.
Who is that tall person?
This is a song I like.
On rainy days, I read books at home.
What he says is right.
Is there anyone who understands Japanese?
The が that goes with 分かる, できる and "can" forms changes in the same way.
When it stays が
When an object comes between
の wants its verb or adjective close behind it. With an object in between, の joins onto that noun and reads as "'s" or "of".
This park is where my father took the photo.
My father took it.
This park is where the photo of my father was taken.
父の写真 now reads as one thing, a photo of my father. Who took it isn't said.
In the main part of a sentence
Not said: この
(My mother made this cake.)
母が作りました. The switch is only for the inside of a description.
Close neighbours
昨日買った本N5
How a description goes before a noun in the first place. Inside it, the one who does it takes が, not は.
I ate the cake my friend made.
