加上
jiāshàng · HSK 5
in addition (to)
➕ 加 = add + 上 = on/onto; 'add on top' = in addition (to)
加 means 'add' and 上 literally means 'up/on'. Together 加上 = 'add on top of', which extends naturally to the abstract sense 'in addition to'. Common before listing an extra factor or item.
加 — force 力 + mouth 口
加 is traditionally analyzed as a compound of 力 (strength) and 口 (mouth), suggesting boasting or exaggerating one's effort with words. From this it extended to the meaning 'to add' or 'increase'. Today it is used broadly for addition, both literal and figurative.
上 — horizontal line above a baseline
上 is an indicative character (指事): a short stroke placed above a longer reference line shows the concept of 'above' or 'up'. The earliest oracle-bone forms used two horizontal lines for this; the modern shape added a vertical stroke for clarity. The core meaning of 'upper, above, to ascend' has stayed stable for millennia.
