Questions & Answers about shoten de saifu o sagashite itara, denchi mo yasuku utte imashita.

What does で indicate in “書店で”?

The particle で marks the location where an action takes place. Here, it shows that you were at the bookstore when you were doing the searching.

Why is 財布 followed by を in “財布を探していたら”?

探す is a transitive verb meaning “to look for.” The object you’re searching for (the wallet) takes the particle を, indicating what is being looked for.

What is the function of 探していたら?

This is the past progressive form (探していた) plus the conditional ら. Together, it means “while/when I was searching…” and implies that something unexpected happened (in this case, finding cheap batteries).

How does も work in “電池も安く売っていました”?

も adds the meaning of “also” or “too.” It indicates that in addition to wallets, batteries were also being sold cheaply.

Why is it 売っていました instead of just 売った or 売ます?

売っていました is the past progressive (売っている → selling) in past form. It suggests that at that time, the store had batteries on sale and they were there for purchase—an ongoing or habitual state in the past.
