Questions & Answers about chizu o yoku mireba, michi ga sugu wakarimasu.

What does 見れば mean here?

見れば is the conditional form of 見る (to look / to see).

So:

• 見る = to look
• 見れば = if you look

In this sentence, it sets up a condition:

• 地図をよく見れば = if you look carefully at the map

This is the -eba conditional, which often sounds a little like if X, then Y.

Why is there を after 地図?

を marks the direct object of the verb 見る.

Here, the thing being looked at is 地図 (map), so:

• 地図を見ます = look at the map

Even though English uses at in look at the map, Japanese simply uses を with 見る.

Why is there が after 道 instead of を?
