Translation:My sibling pours oil on the table.
"Sibling" is now accepted. I was wondering, though, whether Hungarians use "testvér" as often as implied by Duolingo. Most native English speakers would not even know of the word until they reach high school and meet it in a technical context. Normally, your mother would call out "Hey Greg, where are your brothers and sisters?", never "Where are your siblings?".
