Индейка оказалась мягче курицы, и даже младшая дочь съела весь гарнир.

Оказалась means turned out to be or proved to be, not just was.

So:

• Индейка была мягче курицы = The turkey was softer than the chicken.
• Индейка оказалась мягче курицы = The turkey turned out to be softer than the chicken.

This suggests some result, discovery, or mild surprise.

Also, оказалась is:

• past tense
• feminine singular

because индейка is a feminine singular noun.

In this sentence, индейка most naturally means turkey meat, because the sentence is talking about how soft it was and about eating a side dish.

Russian often uses the same noun for the animal and the meat, depending on context.

So here:

• индейка = turkey, as food
• курицы also refers naturally to chicken meat, not just the animal

The -ся part is a common Russian ending that can have different functions. In оказаться, it is part of the verb itself.

The verb pair is roughly:

• оказываться = to turn out, to prove to be
• оказаться = to turn out, to prove to be, in the perfective sense

In this sentence, оказалась is the feminine past form of оказаться.

You do not need to translate -ся separately here. It is just part of the verb оказаться.

Yes. Мягче means softer and is the comparative of мягкий = soft.

So:

• мягкий = soft
• мягче = softer

Russian comparatives are often formed as single words, unlike English, which uses more with many adjectives.

This comparative is a little irregular in form, so it is best learned as a vocabulary item:

• мягкий → мягче

After a comparative like мягче = softer, Russian often puts the thing being compared in the genitive case.

So:

• мягче курицы = softer than chicken

Here, курицы is the genitive singular of курица.

Another possible pattern in Russian is:

• мягче, чем курица

which also means softer than chicken.

So the sentence uses one standard comparison pattern:

• comparative + genitive

Yes, that would be grammatical.

You can compare in two common ways:

• мягче курицы
• мягче, чем курица

Both mean softer than chicken.

The version without чем is very common and often a bit more compact. In simple comparisons, Russian often prefers this structure.

Младший / младшая is used for younger in relation to age within a family or group.

So:

• младшая дочь = younger daughter / youngest daughter
• молодая дочь would sound unnatural here, because молодой means young, not younger than someone else in the family

Use младший when comparing siblings or family members by age.

It can mean either, depending on context.

• If there are two daughters, младшая дочь usually means the younger daughter.
• If there are more than two, it can mean the youngest daughter.

Russian does not always force that distinction as clearly as English does. The broader context usually makes it clear.

Даже means even.

It adds emphasis and suggests surprise:

• и даже младшая дочь съела весь гарнир = and even the younger daughter ate the whole side dish

This implies that maybe the younger daughter is picky, eats less, or was not expected to finish it.

So даже highlights that this fact is a little unexpected.

Съела is the past tense of the perfective verb съесть, which means to eat up, to finish eating.

So:

• ела = was eating / ate, with no focus on completion
• съела = ate up / finished eating

Because the sentence says весь гарнир = the whole side dish, the perfective verb fits very naturally. It shows the action was completed.

Also, съела is feminine singular because дочь is feminine singular.

Весь means all or the whole.

So:

• весь гарнир = the whole side dish / all the side dish

It agrees with гарнир, which is:

• masculine
• singular
• inanimate

Here гарнир is the direct object of съела, so it is in the accusative case. But for masculine inanimate nouns, the accusative looks the same as the nominative:

• nominative: гарнир
• accusative: гарнир

And the adjective matches it:

• весь гарнир

Not usually in the English sense.

Russian гарнир normally means a side dish, such as rice, potatoes, vegetables, and so on, served with the main dish.

So in this sentence, весь гарнир is better understood as:

• the whole side dish
• not just a small decorative garnish

This is a useful false-friend warning for English speakers.

Yes, Russian word order is fairly flexible, but changing it changes the emphasis.

This version puts focus on даже младшая дочь as the surprising part:

• и даже младшая дочь съела весь гарнир

You could also hear other orders, for example:

• и младшая дочь даже съела весь гарнир
• и весь гарнир съела даже младшая дочь

These are all grammatical, but they emphasize different parts of the sentence. The given version sounds natural and clearly highlights even the younger daughter.

Because each verb agrees with its subject in the Russian past tense.

1. Индейка оказалась

   • индейка is feminine singular
   • so the verb is оказалась

2. младшая дочь съела

   • дочь is feminine singular
   • so the verb is съела

In Russian past tense, verbs show gender in the singular:

• masculine: no final -а
• feminine: -а
• neuter: -о
• plural: -и

So this sentence is a good example of past-tense gender agreement.
