How do you say i buy expensive lollies in hiragana?

There's no direct translation for "lollies" in Japanese. Here's how you can say "I buy expensive candy" in Hiragana:

わたしは、たかい あめ を かいます。 (watashi wa, takai ame o kaimasu)

Let's break it down:

* わたし (watashi) - I

* は (wa) - particle indicating the subject

* たかい (takai) - expensive

* あめ (ame) - candy

* を (o) - particle indicating the object

* かいます (kaimasu) - I buy

Other ways to say "candy":

* お菓子 (okashi) - This is a more general term for "sweets" or "confectionery"

* キャンディー (kyandie) - This is the Japanese pronunciation of "candy"

So you could also say:

* わたしは、たかい お菓子 を かいます。 (watashi wa, takai okashi o kaimasu) - I buy expensive sweets.

* わたしは、たかい キャンディー を かいます。 (watashi wa, takai kyandie o kaimasu) - I buy expensive candy.
