In my language(Romanian), the numbers between 11 and 19 are onetoten,(unsprezece) twototen(doisprezece) … Ninetoten(nouasprezece)
There are 3 exceptions: for 11 instead of unusprezece(onetoten) its unsprezece(un/o is used when saying that there is only one of something, but unu is used when counting), for 14 instead of patrusprezece(fourtoten) its paisprezece and instead of sasesprezece(sixtoten) its saisprezece
