Questions & Answers about Mióta tudok fókuszálni, ritkán van bemozdulás.

What does mióta mean here?

Here mióta introduces a time clause and means since.

So Mióta tudok fókuszálni means roughly since I’ve been able to focus or ever since I learned to focus.

A useful thing to know is that mióta can also appear in questions, where it means since when? or for how long?
For example:

• Mióta laksz itt? = How long have you lived here?

But in your sentence it is not a question word; it is a conjunction introducing the first clause.

Should it be mióta or amióta?

Both are possible.

• amióta is the fuller form and often sounds a bit more explicit or standard in careful language
• mióta is also very common and natural

So:

• Amióta tudok fókuszálni, ritkán van bemozdulás.
• Mióta tudok fókuszálni, ritkán van bemozdulás.

Both work. A learner will often meet amióta in textbooks, but real speech very often has mióta.

Why is tudok in the present tense? English often uses a present perfect with since.
