Один из гостей попросил ещё немного зелени к горячему блюду.

Один из гостей means one of the guests.

Russian often uses the pattern один из + genitive plural to mean one of the...:

• один из студентов = one of the students
• одна из книг = one of the books
• одно из окон = one of the windows

Here, гостей is the genitive plural of гости.

Also, один is masculine because the person being talked about is male, which matches the verb попросил. If it were a woman, you would say Одна из гостей попросила...

Because of из.

The preposition из often means from, out of, or from among, and it requires the genitive case. In the fixed pattern один из..., the noun after it is normally in the genitive plural:

• один из друзей
• один из учителей
• один из гостей

So гостей is not random: it is exactly the form Russian grammar requires after из in this structure.

Попросил is the past tense, masculine singular, perfective form of попросить.

It tells you three things:

1. Past tense: the action happened in the past.
2. Masculine singular: the subject is one male person.
3. Perfective: the request is seen as a single completed action.

So попросил fits very naturally here: one male guest made a request once.

This is an aspect question.

• попросил = perfective → he asked / made a request
• просил = imperfective → he was asking, used to ask, or the focus is on the process/repetition rather than the completed request

In this sentence, попросил is the normal choice because the speaker is describing one completed event.

Compare:

• Один из гостей попросил зелени. = One of the guests asked for some herbs/greens.
• Один из гостей просил зелени. = One of the guests was asking for herbs / had been asking for herbs.

Because Russian does not always use a preposition where English does.

In English, you usually say ask for something. In Russian, попросить can often take the thing requested directly, without a separate word meaning for.

Examples:

• попросить счёт = to ask for the bill
• попросить помощи = to ask for help
• попросить воды = to ask for water

So in this sentence, попросил ещё немного зелени is a normal Russian way to say asked for some more greens/herbs.

One subtle point: the noun after попросить is not always in the same case. It depends on the noun and the meaning. Here зелени is genitive because of the quantity expression немного.

Because немного normally requires the genitive case.

This is very common in Russian with words of quantity:

• немного воды = a little water
• немного сахара = a little sugar
• немного времени = a little time
• немного зелени = a little greenery/herbs

The basic dictionary form is зелень, but after немного it becomes зелени.

So the structure is:

• ещё = more
• немного = a little
• зелени = of greens/herbs

Together: ещё немного зелени = a little more greens/herbs

In a food context, зелень usually means fresh herbs / leafy greens used as garnish or accompaniment.

It can refer to things like:

• dill
• parsley
• cilantro/coriander
• green onions
• similar fresh greens

So here it probably means something like some more herbs/greens to go with the dish.

Yes, outside a food context зелень can mean greenery in the general sense, like plants or green foliage. But in restaurant or cooking language, it very often means fresh herbs/greens.

Here ещё means more.

Russian ещё can have several meanings depending on context:

• still
• yet
• more / another

In ещё немного зелени, it clearly means a little more.

Compare:

• Он ещё спит. = He is still sleeping.
• Хочешь ещё чаю? = Do you want more tea?
• ещё немного = a little more

So in this sentence, ещё modifies the quantity expression немного.

Here к means something like for or with in the sense of to go with.

Literally, к often means to or toward, but with food it is commonly used for accompaniment:

• соус к мясу = sauce for the meat
• чай к десерту = tea with / for dessert
• гарнир к рыбе = a side dish for fish
• зелень к блюду = greens/herbs for the dish

So к горячему блюду means for the hot dish or to go with the hot dish.

It does not mean movement here.

Because к requires the dative case, and the adjective must agree with the noun.

The dictionary forms are:

• горячее = hot
• блюдо = dish

After к, they change to dative singular:

• горячему
• блюду

So:

• горячее блюдо = hot dish
• к горячему блюду = for/to the hot dish

The adjective горячему agrees with блюду in case, number, and gender.

It can mean both, depending on context.

Literally, горячее блюдо means hot dish. But in restaurant language, Russian speakers often use горячее for the hot main course or entrée, especially in contrast with things like:

• закуска = appetizer
• салат = salad
• суп = soup
• десерт = dessert

So in this sentence, к горячему блюду could mean:

• with the hot dish
• with the main hot course

The exact English translation depends on the situation.

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

This sentence has a fairly neutral order:

Один из гостей попросил ещё немного зелени к горячему блюду.

But Russian could rearrange parts for emphasis. For example:

• Ещё немного зелени один из гостей попросил к горячему блюду.
  This puts emphasis on ещё немного зелени.

• К горячему блюду один из гостей попросил ещё немного зелени.
  This highlights what the herbs were for.

The original version is a natural, neutral way to say it.

Yes. It is pronounced yo, so ещё sounds like ishchó or yeshchó, not like a plain е word.

In many printed texts, Russians often write еще without the dots, but the meaning and pronunciation are still ещё.

For a learner, it is helpful to remember:

• ещё = pronounced with ё
• when you see еще in a normal text, it usually still means ещё

So even if the dots are omitted in writing, the pronunciation does not change.
