Inherited from Ottoman Turkish ایرمك (ermek, “to attain, reach, mature”), from Proto-Turkic *ẹ̄r- (“to reach”).
Cognate with Old Uyghur (er-, “to reach”) and (ert-, “to pass”), Azerbaijani ermək, and Khalaj (ẹ̄̂r-, “to reach”).
Possibly cognate with Hungarian ér (“to reach”), thought to be a Turkic borrowing, and, according to Nişanyan, Old Turkic (er-, “to be”). See more at imek.
