çekim: çoğul tensões

köken: Borrowed from Latin tēnsiōnem (“stretching; tension”), from tendō (“to stretch”), ultimately from Proto-Indo-European *ten- (“to stretch, draw”). Doublet of the inherited tesão.

çekim: çoğul καταπονήσεις · tamlayan καταπόνησης
köken: Learned borrowing from Koine Greek καταπόνησις (katapónēsis, “oppression”) with semantic loan from French fatigue. By surface analysis, καταπονη- (stem of καταπονώ (kataponó)) + -ση (-si)
köken: From an Oghur language before the times of the Hungarian conquest of the Carpathian Basin at the turn of the 9th and 10th centuries, from Proto-Turkic *erk (“strength, might, will, power”).
