Vocabulary is commonly defined as all the words known and used by a particular person. Knowing a word, however, is not as simple as merely being able to recognize or use it. There are several aspects of word knowledge that are used to measure word knowledge.
For other uses, see Word (disambiguation). In linguistics, a word is the smallest element that can be uttered in isolation with semantic or pragmatic content (with literal or practical meaning). This contrasts deeply with a morpheme, which is the smallest unit of meaning but will not necessarily stand on its own.
