Question

misgiving什么时候用单数，什么时候用复数

Answer 1

一、绝大多数的可数名词的复数形式，是在该词末尾加上后辍-s。
读音变化：结尾是清辅音读[s]，结尾是浊辅音或元音读[z]。
例：friend→friends;
cat
→cats; style→styles; sport→sports; piece→pieces
二、凡是以s、z、x、ch、sh结尾的词，在该词末尾加上后辍-es构成复数。
读音变化：统一加读[iz]。
例：bus→buses; quiz→quizzes; fox→foxes; match→matches; flash→flashes
三、以辅音字母+y结尾的名词
misgiving这个单词的复数，单数意义差不多，有时候做可数，有时候不可数。一般搭配得当即可，没有具体的分区。

— usually plural
Many people have expressed (deep/serious/grave) misgivings about her qualifications for the job.
