The present perfect: hafa (or vera for motion verbs) + the supine. Ég hef borðað.
I can say what I have done and where I have been (Ég hef farið til Íslands).
Look at these examples. Can you spot the grammar pattern?
Ég hef borðað hákarl.
I have eaten fermented shark.
Hún hefur séð norðurljósin.
She has seen the northern lights.
Ég er kominn heim.
I have come home.
Hefur þú farið til Íslands?
Have you been to Iceland?
Pay attention to the highlighted parts. What do they have in common?
To say something has happened, Icelandic uses hafa + the supine (the -ð/-t form you met with geta):
A small group of motion/change verbs uses vera instead of hafa, and then the form behaves like an adjective and agrees: Ég er kominn (m) / komin (f) - I have arrived; Hún er farin - she is now gone.
Tip: the same motion verb can take either auxiliary - hafa for the experience (ég hef farið til Akureyrar = I have been to Akureyri) and vera for the resulting state (hún er farin = she is away now). Don't force vera onto every past action.
English (have eaten) and German (habe gegessen) work the same way. Russian and Ukrainian have no perfect tense - they use verbal aspect instead - so for those speakers this is a genuinely new structure: hafa + supine, not a past form.

Practice ExercisesUsing a past form instead of the supine after hafa (Ég hef *borðaði instead of hef borðað). - Using hafa where vera is needed for motion/change verbs (Ég hef *kominn -> Ég er kominn). - Not agreeing the vera-form for gender (kona segir 'ég er komin', not kominn). - Russian/Ukrainian speakers reaching for aspect instead of building hafa + supine.
Ég hef borðað hákarl.
I have eaten fermented shark.
hafa + supine borðað.
Hún hefur séð norðurljósin.
She has seen the northern lights.
hefur + supine séð (from sjá).
Ég er kominn heim.
I have come home.
Motion verb koma uses vera + kominn, which agrees (m kominn / f komin).
Hefur þú farið til Íslands?
Have you been to Iceland?
Question: hefur þú + supine farið.
