Questions & Answers about pegu wa koko ni aru.

Why is ペグ written in katakana?

ペグ is written in katakana because it is a loanword, probably borrowed from English peg.

In Japanese:

• hiragana is mainly used for native grammar words and some native words
• katakana is often used for foreign loanwords, sound effects, and emphasis
• kanji is used for many native and Sino-Japanese words

So ペグ being in katakana signals that it is not a traditional native Japanese word.

What does は do in this sentence?

は marks ペグ as the topic of the sentence.

So ペグは means something like:

• as for the peg,
• the peg

This does not always match English subject exactly. The topic is what the sentence is about.

So:

ペグは ここに ある。
= As for the peg, it is here.

The sentence is telling you where the peg is.

Why is は pronounced wa even though it looks like ha?
