Questions & Answers about Ég tek ruslið út í kvöld.

Why is Ég included? Can I drop the subject pronoun?

Yes, you can often drop ég in Icelandic because the verb ending usually makes the subject clear:

• Tek ruslið út í kvöld. = (I) take the trash out tonight.
  Including Ég is still normal for emphasis, contrast, or clarity (e.g., Ég tek ruslið út, en þú þværð upp.).

What does tek tell me грамmatically?

Tek is the 1st person singular present tense form of the verb taka (to take).
Present tense in Icelandic often covers both I take and I am taking, depending on context.

Why is it ruslið and not just rusl?

rusl means trash/garbage (uncountable). ruslið is the trash with the definite article attached as a suffix (-ið here).
In everyday speech, Icelandic often uses the definite form in situations where English might say the implicitly: take out the trash → taka ruslið út.
