One meaning of nitty-gritty is the most important part or basic truth of any situation or subject. But, if you are not a fan of rhyming compounds or if you need to use a more formal word, you can use many other English expressions. ________________________________"Nitty-gritty"的意思之一就是事物中最基本或者最重要的部分.但是,如果你不热衷于使用叠韵词或者需要用更加正式的词语,你可以用其他的方式来表达.___________________________
