Although most crocodiles eat about 50 meals a year, they can survive a whole year, and sometimes even two or three years, without eating anything.
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.
A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which list every single object that a term describes).
