An Old English noun has two parts which you must note: it has a stem, which contains the noun's basic meaning and its gender; and it also has a case ending which tells you the noun's case and its number. A pattern of endings which are added to the end of a noun to show its grammatical function is called a declension. Each noun in Old English belongs to one declension.The most common declensions are called the masculine a-, neuter a-, feminine o-, weak masculine -n and weak feminine -n declensions. There are a few other declensions, but these are uncommon and we can ignore them for the time being.
