Over There
noun, pronoun, こそあど word
Remember how words beginning with あ show that whatever you're talking about is far away from both you and the person you're talking to? And how words ending in こ refer to places? So what do you think this means? That right, it's over there.
Note that even though あそこ means "over there," it's still used to refer to a specific, concrete place, as opposed to a word like 向こう which means "over there" in a broader, more general sense.
私のうちは、あそこだよ。
My house is over there.
あそこでちょっと休もう!
Let's take a short rest over there!
あそこにあるのは何?
What's that thing over there?
