IPA: /ˈsɛvən/
KK: /sɛvən/
A number that comes after six and before eight, representing a quantity of seven.
There are seven days in a week.
The word 'seven' originates from Old English 'seofon', which is derived from Proto-Germanic '*sebun', meaning the number following six. It is related to similar words in other Germanic languages, such as Old High German 'sibun' and Old Norse 'sjau'.
Think of the Old English 'seofon' as the number that comes after six — that's how you remember that 'seven' is the number after six.
