Original sentence: Classifiers are most often used when counting.However, it must be noted that not all classifiers are strictly measure words.In Chinese, for example, classifiers are also used with determiners such as "this", "that", etc.........Measure word.Their use is thus analogous to English words that represent units or portions of mass nouns, for example one drop of milk, fifty head of cattle, three pieces of cake.This particular type of classifier is called a measure word, as well as a counter or counting word
Edited sentence: Classifiers are distinguished from measure words.While classifiers are used to count or identify individual occurrences of a count noun and usually have no direct translation in English, measure words count mass nouns by dividing them into portions (as in one drop of mud; because "mud" is a mass noun, *one mud is ungrammatical) or grouping them into containers (as in one glass of water)
