Исполнитель проверил целевой язык и память переводов.

Проверил is the perfective past form of проверить, so it presents the action as completed: the person checked it and finished checking it.

If you used проверял instead, that would be the imperfective past of проверять, which would sound more like:

• he was checking
• he used to check
• he checked in the sense of focusing on the process, not the completed result

So in this sentence, проверил is the natural choice if the point is that the check was successfully carried out.

In the Russian past tense, the verb agrees with the subject in gender and number.

Here:

• проверил = masculine singular
• проверила = feminine singular
• проверило = neuter singular
• проверили = plural

So проверил tells you that the subject is grammatically masculine singular. That matches исполнитель, which is a masculine noun.

It is in the accusative case, because it is a direct object of проверил.

However, for an inanimate masculine singular noun like язык, the accusative looks exactly like the nominative:

• nominative: целевой язык
• accusative: целевой язык

So even though the form does not change, the function in the sentence is accusative.

Yes, память is also in the accusative case, because it is the second direct object of проверил.

For many feminine nouns ending in -ь, the accusative singular is the same as the nominative singular:

• nominative: память
• accusative: память

So both целевой язык and память переводов are objects of the verb.

Память переводов is the standard Russian term for translation memory.

Literally, it means memory of translations, so:

• память = memory
• переводов = of translations

Переводов is genitive plural.

If you said память перевода, that would sound more like the memory of a translation or a translation's memory, which is not the normal technical term in CAT-tool / localization contexts.

Because it depends on the noun память.

Russian often links two nouns by putting the second noun in the genitive, roughly like English of:

• память переводов = memory of translations

It is plural because the term refers to a collection/database of many translated segments, not just one translation.

Исполнитель is a broad word. Depending on context, it can mean:

• performer
• executor
• contractor
• assignee
• the person carrying out a task

In a translation or localization context, it often means the person doing the job, such as a translator, editor, or vendor. Russian often uses general administrative words like this where English might choose a more specific word.

Yes. Целевой язык is the normal term for target language.

The adjective целевой means something like:

• target
• intended
• aimed at a goal

A common opposite would be:

• исходный язык = source language
• sometimes язык оригинала = original language

So this is standard technical vocabulary.

Because Russian does not have articles.

English says things like:

• the target language
• a translation memory

Russian normally expresses that meaning through context instead. So:

• целевой язык can mean the target language or a target language
• память переводов can mean the translation memory or a translation memory

The surrounding context tells you which is meant.

This word order is the neutral, straightforward one:

Исполнитель + проверил + целевой язык и память переводов

That is basically: subject + verb + object

Russian word order is more flexible than English, so other orders are possible for emphasis or contrast. But this version sounds natural and neutral, especially in technical or professional writing.

Yes. И means and, and here it joins two direct objects of проверил:

• целевой язык
• память переводов

So the sentence says that the person checked both the target language and the translation memory.

Yes, язык can mean either tongue or language.

But in this sentence, целевой язык is clearly the technical phrase meaning target language, so there is no ambiguity in context.
