Повесь мокрую футболку на вешалку, чтобы она быстрее высохла.

Повесь is the singular informal imperative of повесить.

So the base verb is:

• повесить = to hang up, to put something up so that it hangs

And the imperative:

• повесь! = hang it up!

This form is used when speaking to one person in an informal way, like to a friend, child, family member, or someone you address with ты.

A few related forms:

• повесь = hang it up! (to one person, informal)
• повесьте = hang it up! (to several people, or one person formally)
• вешай = keep hanging / hang it (imperfective, often more about process or repeated action)

In this sentence, повесь sounds natural because it refers to one complete action: put the T-shirt on the hanger.

Because футболку is the direct object of the verb повесь, so it must be in the accusative case.

The dictionary form is:

• мокрая футболка = a wet T-shirt

But after a transitive verb like повесить (to hang up something), you need the accusative:

• мокрую футболку = the wet T-shirt

Both words change because мокрая agrees with футболка.

Feminine singular forms here are:

• nominative: мокрая футболка
• accusative: мокрую футболку

This is very common in Russian: adjectives change along with the noun.

Because this sentence describes motion toward a destination, not location.

Russian often distinguishes between:

• куда? = where to? → accusative after на
• где? = where? → prepositional after на

So:

• на вешалку = onto the hanger / to the hanger
• на вешалке = on the hanger

Compare:

• Повесь футболку на вешалку. = Hang the T-shirt on the hanger.
• Футболка висит на вешалке. = The T-shirt is hanging on the hanger.

So the accusative вешалку is used because the shirt is being moved onto it.

Here вешалка means a clothes hanger.

Depending on context, вешалка can sometimes mean:

• a hanger
• a coat rack
• a place for hanging clothes

But in this sentence, because you are hanging a футболка so it dries, the natural meaning is clothes hanger.

So:

• на вешалку = on a hanger

Чтобы introduces a clause of purpose or desired result.

Here it means:

• so that
• in order that

So:

• Повесь мокрую футболку на вешалку, чтобы она быстрее высохла.
• Hang the wet T-shirt on a hanger so that it dries faster.

This is a very common Russian structure:

• Сделай X, чтобы Y.
• Do X so that Y happens.

Examples:

• Открой окно, чтобы проветрить комнату.

• Open the window to air out the room.

• Напиши мне, чтобы я не забыл.
• Write to me so that I don’t forget.

Because она refers to футболка, and футболка is a feminine noun.

In Russian, pronouns agree with the grammatical gender of the noun:

• он = masculine
• она = feminine
• оно = neuter
• они = plural

Since футболка is feminine, Russian uses:

• она быстрее высохла = so that it dries faster

Even though in English we usually say it for things, Russian uses the noun’s grammatical gender, so она is completely normal here.

Because it agrees with она, which refers to футболка.

The verb высохнуть means to dry out / to become dry. In the past tense, Russian verbs change by gender in the singular:

• высох = masculine
• высохла = feminine
• высохло = neuter
• высохли = plural

Since the subject is она = the T-shirt, feminine, the form must be:

• она высохла

This is one of the things English speakers often notice, because English past tense verbs do not change for gender, but Russian ones do.

Because высохла expresses the idea of becoming dry completely / ending up dry, which fits the sentence better.

Compare the two verbs:

• сохнуть = to be drying, to dry
• высохнуть = to dry out, to become dry completely

In this sentence, the point is the result:

• hang it up so that it dries fully
• not just so that it is in the process of drying

That is why the perfective verb высохнуть is natural here, and its past form высохла appears after чтобы.

This is a very common Russian pattern.

After чтобы, Russian often uses a form that looks like the past tense, especially with a perfective verb, even when the meaning is about a future desired result.

So:

• чтобы она быстрее высохла

does not mean the drying happened in the past. It means:

• so that she/it will dry faster
• so that it ends up drying faster

This structure is normal Russian grammar. English learners often expect a future form here, but Russian usually does not use a future tense after чтобы in this type of sentence.

Быстрее means faster.

It is the comparative form of быстро (quickly / fast).

So:

• быстро = quickly
• быстрее = more quickly / faster

In this sentence:

• чтобы она быстрее высохла = so that it dries faster

Russian often uses these short comparative forms very naturally in everyday speech.

Examples:

• Говори медленнее. = Speak more slowly.
• Пиши аккуратнее. = Write more neatly.
• Иди быстрее. = Go faster.

Yes, but the sentence is also fairly neutral.

The basic structure is:

• Повесь мокрую футболку на вешалку
• чтобы она быстрее высохла

This is a natural order:

1. command
2. purpose/result clause

Within the first part:

• мокрую футболку comes before на вешалку because first you mention what to hang, then where to hang it.

Within the second part:

• она = subject
• быстрее = adverb
• высохла = verb

That is a normal and clear order in Russian.

Russian word order is flexible, but this version sounds natural and unmarked.

Not naturally in this context.

• суше means drier, not dry faster
• сохла быстрее would mean was drying faster, focusing more on the process, and it sounds less suitable here

The sentence wants to express the goal that the T-shirt become dry sooner, so:

• чтобы она быстрее высохла

is the best choice.

It combines:

• быстрее = faster
• высохла = became dry / dried out

So the whole phrase means the shirt will reach the dry state more quickly.

Not necessarily. In Russian, imperatives are used very normally, and they do not automatically sound rude.

Whether повесь sounds fine or rude depends on:

• who is speaking
• tone of voice
• relationship between speakers
• context

For example, between family members or friends, Повесь мокрую футболку на вешалку can sound perfectly ordinary.

If you wanted to make it softer, Russian has other options, such as:

• Повесь, пожалуйста, мокрую футболку на вешалку.
• Please hang the wet T-shirt on a hanger.

So the imperative itself is neutral; politeness depends on context and wording.
