In speech, the numbers 14 and 40 are often confused. When carefully enunciated, they differ in which syllable is stressed: 14 i/fɔərˈtiːn/ vs 40 /ˈfɔrti/. When being related to the word "four" (4), 14 is spelled "fourteen", and not "forteen". However, in dates such as 1492 or when contrasting numbers in the teens, such as 13, 14, 15, the stress shifts to the first syllable: 14 /ˈfɔərtiːn/.
