両側
りょうがわ · ryougawa · JLPT N2 · noun
side
両 (both) + 側 (side): 'both sides', read ryou-gawa, where 両 means a pair and 側 means side
両 means a pair or both, and 側 means side, so the compound literally reads as 'both sides'. Note the sound change: 両側 is pronounced ryougawa, with the 'k' of kawa softened to 'g'.
