Questions & Answers about pan o yoku kande kudasai.

What does を do in this sentence?

を marks パン as the direct object of the verb. In other words, it shows that bread is the thing being chewed.

So in:

パンをよく噛んでください。

the structure is basically:

• パン = bread
• を = object marker
• よく噛んでください = please chew well / please chew thoroughly

Why is パン written in katakana?

パン is the normal Japanese word for bread, and it is written in katakana because it is a borrowed word.

Even though many loanwords in Japanese come from English, パン actually comes from Portuguese pão.

So this is just the standard way to write the word. It is not especially formal or unusual.

What does よく mean here?

Here, よく means well or thoroughly.

So it tells you how to chew: chew carefully / chew thoroughly.

This is important because よく can also mean often in other sentences. For example:

• よく行きます = I go often

But in this sentence, with 噛む (to chew), it clearly means well/thoroughly, not often.
