Questions & Answers about daidokoro no jaguchi ga shikkari shimaranai node, kanrigaisha ni renrakushimashita

Why is の used in 台所の蛇口?

の links two nouns and often works like of or 's in English.

• 台所 = kitchen
• 蛇口 = faucet / tap
• 台所の蛇口 = the kitchen faucet

So here, の shows that the faucet belongs to or is located in the kitchen.

Why is it 蛇口が and not 蛇口は?

が marks 蛇口 as the thing experiencing the problem: the faucet is the thing that doesn't close properly.

With が, the sentence focuses on what is happening with the faucet itself.

• 蛇口が閉まらない = the faucet won't close

If you used は, it would sound more like setting up the faucet as the topic for contrast or discussion:

• 蛇口は閉まらない = as for the faucet, it won't close

That is possible in some contexts, but が is very natural when simply describing the issue.
