Летом я часто ношу шорты и лёгкую майку дома.

Летом is the normal Russian way to say in summer when talking about time.

Russian often uses the instrumental case for seasons in this adverb-like meaning:

• летом = in summer
• зимой = in winter
• весной = in spring
• осенью = in autumn

So Летом я часто ношу... means In summer, I often wear...

Using в лето would sound wrong here.
Using в лете is also not how modern Russian expresses this idea.

This is a very common question, because Russian distinguishes between:

• носить = to wear, to have on regularly
• надевать = to put on

In this sentence, the meaning is habitual: the speaker is talking about what they usually wear in summer. So ношу is correct.

Compare:

• Я ношу шорты дома. = I wear shorts at home.
• Я надеваю шорты. = I am putting on shorts.

So ношу focuses on the state or habit of wearing, not the action of dressing.

In Russian, шорты is normally a plural-only noun. It works like English shorts.

So you say:

• эти шорты = these shorts
• новые шорты = new shorts
• ношу шорты = I wear shorts

There is no normal singular form meaning one pair of shorts in everyday usage.

Because майку is the direct object of the verb ношу, it must be in the accusative case.

The dictionary form is:

• лёгкая майка

But in the accusative singular feminine, both words change:

• лёгкая → лёгкую
• майка → майку

So:

• я ношу лёгкую майку

This is adjective agreement in action: the adjective changes to match the noun in gender, number, and case.

Because they behave differently in the accusative.

• шорты is plural and inanimate
• майка is feminine singular

For inanimate plural nouns, the accusative is usually the same as the nominative:

• nominative: шорты
• accusative: шорты

But for a feminine singular noun like майка, the accusative is different:

• nominative: майка
• accusative: майку

So in the same sentence you get:

• ношу шорты
• ношу майку

Дома is a very common adverb meaning at home.

So:

• я дома = I am at home
• ношу шорты дома = I wear shorts at home

By contrast, в доме literally means in the house/building. It usually focuses more on the physical location inside a house or building, not simply the idea of being at home.

Compare:

• Я дома. = I’m at home.
• Я в доме. = I’m in the house.

Also useful:

• дома = at home
• домой = home, toward home

So:

• Я дома. = I’m at home.
• Я иду домой. = I’m going home.

Yes. Russian word order is more flexible than English word order.

The sentence Летом я часто ношу шорты и лёгкую майку дома is natural and neutral. But other orders are also possible, depending on emphasis.

For example:

• Я летом часто ношу шорты и лёгкую майку дома.
• Дома летом я часто ношу шорты и лёгкую майку.
• Шорты и лёгкую майку я часто ношу дома летом.

These all express roughly the same basic idea, but the emphasis shifts.

A learner-friendly rule:

• Russian often puts the most important or new information later
• but there is no single fixed order like in English

Yes, often it can.

Russian verbs already show the person and number, so ношу clearly means I wear.

That means you can say:

• Летом часто ношу шорты и лёгкую майку дома.

This is perfectly possible if the subject is obvious from context.

Still, я is not wrong at all. Including it can make the sentence clearer, more explicit, or slightly more contrastive.

No, it does not have to be before the verb, but часто ношу is a very common and natural placement.

In this sentence, часто means often and modifies the whole action of wearing those clothes.

Common placements include:

• я часто ношу...
• я ношу... часто
• часто я ношу...

The most neutral version here is probably я часто ношу...

So yes, its position is somewhat flexible, but some placements sound more natural than others depending on style and emphasis.

Russian has no articles like English a/an or the.

So:

• шорты can mean shorts or the shorts
• лёгкую майку can mean a light tank top or the light tank top

The exact meaning depends on context.

This is normal in Russian, and learners have to get used to understanding definiteness from context rather than from articles.

Майка usually means a tank top, vest, or undershirt, depending on context.

It is not usually the same as футболка, which means T-shirt.

So the sentence specifically suggests something light and sleeveless or very casual, which fits well with summer and being at home.

The letter ё is important here. It is pronounced like yo and is always stressed.

So:

• лёгкую is pronounced roughly LYOHG-ku-yu

A few useful points:

• ё is a separate letter from е
• in many printed texts, Russians often write е instead of ё, even though the pronunciation is still ё
• for learners, it is helpful to notice and learn the correct ё forms

So this word comes from лёгкий = light, and the ё stays part of the word family.

Putting Летом first is very natural because it sets the time frame right away: as for summer / in summer.

Russian often starts sentences with time expressions:

• Сегодня я работаю дома.
• Зимой он много читает.
• Летом я часто ношу шорты...

It is not mandatory, but it is a common and natural way to organize information. English does this too sometimes: In summer, I often wear...
