өрөө

Cognate with Kalmyk өрә (örä, “room, a half of a yurt”) with several possible explanations:

• Deriving from the same root as өрөөл (örööl, “half, one of a pair”), өрөөсөн (öröösön, “odd, unpaired”), originally denoting a half of a yurt.
• From the same root as өр (ör, “interior, heart”).
• өрөх (öröx, “to arrange, to lay”) +‎ -өө(н) (-öö(n)), unlikely due to lack of -n in Kalmyk.
