【The difference】between は (wa) and が (ga) which are subject marking particles



What is the difference between は and が, subject marking particles?


See the two sentences below:

ちち は チョコレート を たべました。

ちち が チョコレート を たべました。

Both of them mean ‘My father ate chocolates.’

The first sentence with は basically just gives you the fact that he ate them.

The second sentence with が implies that the person who ate them is him. Not me, not you, that is him.

There are much more things about は and が, but this is one of the most important aspects you should know.

Use が if you want to make the subject of a sentence specific and exclusive. Other than that, use は.
