The kanji 要 is a pictophonetic compound. The top part is similar to the character 西（せい、にし）, originally depicting a bird's nest. The bottom part depicts 女（じょ、おんな）, meaning "woman." It's believed that the original meaning might have been related to the most important things a woman needed or possessed in ancient times, like a family and a nest. Over time, the meaning broadened to encompass "essential," "necessary," or "important." The 西 component also provides the sound component in the character.
