\r\n Why Is Five Spelled Differently in Fifteen?\r\n <\/p>\r\n\r\n

\r\n Many English learners and native speakers ask how to spell the word 15 and wonder why the base root changes from \"five\" to \"fif-\".\r\n <\/p>\r\n\r\n

\r\n The English language changes some vowels and consonants over time because of historical sound shifts. The Old English form of fifteen was f\u012bft\u012bene<\/em>. When the suffix \"-teen,\" meaning \"ten more than,\" was added to the historical root for five, the word developed into \"fifteen\" rather than \"fiveteen.\"\r\n <\/p>\r\n\r\n

\r\n Remember:<\/strong> The correct spelling is always fifteen<\/strong>, not \"fiveteen.\" Similar spelling changes occur in \"fifty\" and \"fifth.\"\r\n <\/p>\r\n\r\n<\/div>\r\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
