やんだら comes from the verb やむ, which means to stop and is commonly used for things like rain or snow stopping.

Formation:

• やむ → やんだ (plain past)
• やんだ
  • ら → やんだら

So 雨がやんだら means if/when the rain stops.

This 〜たら form often shows a sequence:

1. first, the rain stops
2. then, the speaker puts away the clothespins

Because 雨 is the subject of やむ.

In 雨がやむ, the rain is the thing that stops, so が marks it as the subject.

• 雨がやむ = the rain stops

Using が is very natural in this kind of conditional clause. You might sometimes see は instead, but が is the basic choice here.

This is a very common point of confusion.

In Japanese, 〜たら is made from the past plain form, but that does not automatically mean past time.

So here:

• やんだ is the past form of やむ
• but やんだら means if/when it stops, not if/when it stopped

This is just how the 〜たら conditional is built.

Other examples:

• 食べたら = if/when (someone) eats
• 行ったら = if/when (someone) goes

Because Japanese often uses the plain form inside subordinate clauses like 〜たら, while the final verb shows the overall politeness level of the sentence.

So:

• やんだら = plain form used before 〜たら
• 片付けます = polite main verb at the end

This is completely normal Japanese.

A very common pattern is:

• Xしたら、Yします。

So the sentence can be polite overall even if the earlier verb is plain.

Literally, it is something like the balcony’s clothespins, but in natural English it means more like:

• the clothespins on the balcony
• the balcony clothespins
• the clothespins from the balcony

The particle の connects nouns and lets one noun describe another.

Here:

• ベランダ = balcony / veranda
• 洗濯ばさみ = clothespins

Japanese often uses の where English would use a preposition like on, in, or for, depending on the situation.

洗濯ばさみ means clothespin or laundry clip.

It is made from:

• 洗濯 = laundry
• はさみ = clip / pinching tool / scissors-like thing

The は becomes ば because of a sound change called rendaku, which often happens in compounds.

So:

• はさみ → ばさみ

You do not need to think too hard about the literal parts every time, though. 洗濯ばさみ is best learned as a single vocabulary item.

片付けます means to put away, to tidy up, or to clear away.

In this sentence, it probably means something like:

• I’ll put away the clothespins
• I’ll bring in and put away the clothespins

It is not just look at them or move them slightly. It has the idea of putting things back in order or removing them from where they are.

The plain form is 片付ける.

Because 洗濯ばさみ is the direct object of 片付けます.

• 何を片付けますか。
• 洗濯ばさみを片付けます。

So を marks the thing being put away.

The subject is omitted, which is very normal in Japanese.

From context, it most likely means:

• I will put away the clothespins or possibly
• we will put away the clothespins

Japanese often leaves out subjects when they are obvious from context. English usually requires them, but Japanese does not.

It can mean either, depending on context.

In this sentence, when is probably the most natural translation:

• When the rain stops, I’ll put away the clothespins on the balcony.

Why when? Because the speaker sounds like they expect the rain to stop and then plan to do the next action.

But if is not wrong as a grammar explanation:

• If the rain stops, I’ll put away the clothespins.

So the core idea is:

• after the rain stops / once the rain stops

Normally, no.

Use やむ for rain stopping:

• 雨がやむ
• 雨がやんだら

やめる usually means to stop doing something intentionally, such as:

• たばこをやめる = quit smoking
• 仕事をやめる = quit a job

Rain does not decide to stop, so やめる is not the natural choice here.

A very common written form is also:

• 雨が止んだら

That is the same idea; 止む / 止んだ is often written with the kanji 止.
