The kanji 阿 is a 形声文字 (keisei moji), a phono-semantic compound. It combines the phonetic component 可 (ka, meaning "can") with the radical 阝 (ko), a variant of 阜 (kō, meaning "hill" or "mound," but here representing a location or place). The original meaning may have been related to a location or a person associated with that location. Over time, its meaning shifted to convey familiarity, address, or flattery.
