376: -ty Dec 19, 2015

Everyone learns the number system in preschool and kindergarten, and in comparison to certain other languages (like French) the number system is relatively easy. After the first nine numbers, the larger units (hundreds, thousands) are counted by simply putting a number in front. Decades, and teens are both irregular and due to Old English forms of ten. Fourteen, for example is four+tīen, and the 'ty', or in Old English, 'tig', is another form used for groups of tens.
