Questions & Answers about daikon to hourensou wa reizouko ni aru node, suupaa ni ikanakute sumimashita.

Why is は used after 大根とほうれん草?

は marks 大根とほうれん草 as the topic of the first clause.

So the sentence is structured like:

• 大根とほうれん草は = as for the daikon and spinach
• 冷蔵庫にあるので = since they are in the refrigerator
• スーパーに行かなくて済みました = I didn’t have to go to the supermarket

A learner might expect が instead of は, and が is also possible in some contexts. But は sounds natural here because the sentence is setting up those vegetables as the thing being talked about.

Very roughly:

• 大根とほうれん草は… = speaking of the daikon and spinach...
• 大根とほうれん草が… = the daikon and spinach are the ones that...

In this sentence, は feels more neutral and topic-based.

Why is と used between 大根 and ほうれん草?

と means and when connecting nouns.

So:

• 大根とほうれん草 = daikon and spinach

This is a complete, definite list of the items being mentioned.

If the speaker wanted to mean something more like things like daikon and spinach, they might use や instead:

• 大根やほうれん草 = daikon, spinach, and so on

But here the sentence is specifically talking about those two items, so と is the natural choice.
