Etymology: Kingside is about as transparent as chess terminology gets: it is simply "king" joined to "side," the two halves of the board divided by the line running between the queen and the king. The more interesting thread is in the parts. "King" traces back through Old English "cyning" to a Proto-Germanic form "kuningaz," built on a root meaning "kin" or "race," so a king was, at root, a man of noble lineage. "Side" comes from Old English "sīde," meaning the flank or lateral surface of a body, a sense that survives in the word's ordinary use for the edge of anything. Put together, the compound describes the half of the board where the king stands at the start of a game. Its opposite, queenside, follows the same pattern, pairing a royal name with a direction across the board. The compound is a plain, transparent formation rather than a coinage with a dramatic backstory, so its clearest feature is the way both of its parts keep their old meanings.
