Is wool a countable or uncountable noun?

Answer 1

The noun 'wool' is an uncountablenoun as a word for a substance. Units of wool are expressed as skeins of wool, yards of wool, pounds of wool, etc.

The plural form 'wools' is used for 'types of' or 'kinds of', for example:

"The wools we have available are Shetland and Merino."

Answer 2

The noun 'sheep' is a countable noun but the singular and the plural words are the same.

Example:

The farmer has one black sheep.

The farmer has two white sheep.

An uncountable noun is characterized as having no function (or form) for a plural, or no function (or from) for a singular.

One example is the noun 'oxygen', an uncountable singular noun as a word for a substance. It has no plural form. Quantities of oxygen are expressed as units or amounts, for example a tank of oxygen, two tanks of oxygen. The tanks are counted, not the oxygen.

Another example is the noun 'news', an uncountable plural noun as a type of aggregate noun, a word representing an indefinite number of elements or parts; it has no singular form. Units of news are expressed as the forms in which they are delivered/received, for example a report of news, several reports of news. The reports are counted, not the news.

The sheep can be counted.
