The kanji 塚 is a phono-semantic compound (形声文字, keisei moji). It combines two components: ⚫︎ 阝 (also written as 阜) - on the left, which is a radical often signifying "mound" or "hill." It's derived from a pictograph of a staircase or a hill. ⚫︎豕 (shǐ) - on the right, meaning "pig" or "swine". The original meaning of 豕 might relate to the mound as a pigpen, or a place where pigs are enclosed. It also serves as a phonetic component, giving the kanji its sound.
