Questions & Answers about После ужина я убираю тарелки со стола.

Why is it после ужина and not после ужин?

Because после requires the genitive case.

• Dictionary form: ужин = dinner/supper
• Genitive singular: ужина

So:

• после ужина = after dinner

This is something you simply learn with the preposition:

• до урока = before the lesson
• после работы = after work
• после ужина = after dinner

Why is it убираю, and what aspect is that?

Убираю is the 1st person singular present tense of the imperfective verb убирать.

• убирать = to clear away, tidy up, remove, clean up
• убираю = I clear away / I am clearing away / I usually clear away

Here the imperfective makes sense because the sentence most naturally describes a habitual action:

• После ужина я убираю тарелки со стола.
  = After dinner, I clear the plates from the table.

If you wanted a single completed future action, Russian would usually use the perfective verb:

• После ужина я уберу тарелки со стола.
  = After dinner, I will clear the plates from the table.

Does убираю here mean I am clearing or ?
