The kanji 庫 is a 形声文字 (keisei moji), which means it's a character that combines a semantic component (meaning) with a phonetic component (sound). The left part of the character, 广 (ān), acts as the semantic component and represents a “shelter” or “building.” The right part, 木 (moku), is the phonetic component, initially related to the sound. Thus, 庫 originally depicted a structure, likely a wooden one, used for storage. Over time, the meaning shifted to specifically denote a storehouse or warehouse.
