So, you go back to the old Indo-European root again, and what do you find? The Indo-European stem is pronounced payen -- we would spell it P-A-E-N -- and, lo and behold, mirabile dictu, it is the same root as the word compassion comes from, P-A-E-N.
所以, 你再看看古印欧语系的根源, 你就会发现 --古印欧语系发间为payen -- 我们可以拼写为 P-A-E-N --, 然后看吧, 这个字跟同情这个单词有相同的词根, P-A-E-N.
