少数以-y,-er,ow,-ble结尾的双音节词,末尾加-er（比较级）,-est（最高级）.以-y结尾的词,如-y前是辅音字母,则变y为-i,再加-er和-est.以-e结尾的词只加-r和-st.
【例】 clever cleverer cleverest
narrow narrower narrowest
able abler ablest
easy easier easiest
其它双音节和多音节词皆在前面加单词more和most.
【例】 careful more careful most careful
difficult more difficult most difficult
delicious more delicious most delicious
另外那个什么中华子798你说的问题不存在,patient是有名词病人的意思,但也有形容词耐心的意思,OK?
