The word "妇幼" is formed by combining the character "妇", meaning "woman", which itself is composed of the radical "女" (female) and the component "彐" (derived from a broom symbol, historically indicating domestic roles), with the character "幼", meaning "young" or "child", composed of "幺" (small) and "力" (strength) to convey youth. Together, these characters juxtapose their individual meanings to create a compound word that specifically denotes "women and children".
