英语语法：clothes 和 clothing 可数吗clothes 和 clothing 均可表示“衣服”，用作“衣服”的统称，但在用法上有差别：
hes 是一个没有单数形式的复数名词, 其前不可加不定冠词，也不可加数词，但可用 some, these, those, many, few 等词修饰。如：
正：those clothes / few clothes / many clothes
误：a clothes / two clothes / three clothes
2. clothing 是不可数名词。如：
They wear very little clothing. 他们衣服穿得很少。

Our clothing protects us against the cold. 我们的衣服可以御寒。
We are well provided with food and clothing. 我们吃得好，穿得好。
若不考虑其细微区别，两者常可换用(注：一个是复数，一个不可数)。如：
