Learn Hardcore Russian: Я изучаю грамматику ежедневно.

In Russian, a direct object of a transitive verb takes the accusative case. Here, грамматика is what you’re studying, so it changes from грамматика (nominative) to грамматику (accusative singular feminine).

What’s the difference between изучаю and учу?

Both verbs can translate as “study/learn,” but they differ in nuance. изучать (I study in depth, systematically) vs. учить (I learn something by heart or teach). So изучаю грамматику implies a deeper, structured approach.

Why is изучаю in the imperfective aspect here?

The imperfective aspect expresses ongoing, habitual, or repeated actions. Since you’re describing a routine—“I study grammar daily”—you use imperfective изучаю rather than the perfective изучу, which would imply a one‐time, completed action.

Is there a difference between ежедневно and каждый день?

They both mean “daily” or “every day.”
• ежедневно is a single adverb and sounds slightly more formal.
• каждый день is a phrase (“each day”).
In everyday speech you can use either without changing the core meaning.

Can I move ежедневно to a different position in the sentence?

Yes. Russian word order is relatively free.
For example:
• Я ежедневно изучаю грамматику.
• Ежедневно я изучаю грамматику.
• Изучаю грамматику ежедневно.
All mean the same; changes in position only tweak the emphasis.

Do I have to include я since the verb ending already shows “I”?

No. Russian often omits subject pronouns because the verb ending indicates the person.
Изучаю грамматику ежедневно still means “I study grammar daily.”
Including я simply adds clarity or emphasis.

Why aren’t there articles like “a” or “the” in this sentence?

Russian has no articles. You don’t say a grammar or the grammar—you just use the noun in the correct case. Context fills in whether it’s definite or indefinite.

Could I say Я учусь грамматике ежедневно instead? What’s the nuance?

Yes—учиться takes the dative case (грамматике) and highlights being in the process of learning. изучать + accusative stresses actively studying the subject itself. Both are correct but slightly different in focus.
