爺 ＝ 父 ＋ 耶
ㄧㄝˊ · yé
noun — grandfather; respectful term for an elder man

字源 FORM — what the parts do

父義father (the hand-and-staff household head)
耶聲yé — gives the soundear 耳 plus 阝, borrowed purely for its reading
Father (父) over the top, marking the family-elder sense; 耶 yé sits below for the sound alone. Once a word for father, it climbed a generation to grandfather (爺爺), and widened to any respected elder man (老爺). 耶 runs the series: 椰、揶.

故事 STORY — a scene to remember it by

父（父）的頭頂上再加一輩——爺。
Father (父) with another generation stacked on top — grandfather.
