I don't know why Im like that with the letters. I think its because of all the sounds they make.
I like this to numbers too. For the most part, even numbers are feminine and odds are masculine. 7 is the most interesting, by itsself is masculine. 17, 27, 47, 67, 87, 97 are feminine.(37, 57, and 77 are neuter, exceptions) It "feminizes" numbers. 3 is also interesting, by itsself, it is masculine.
33, 53, 73 are masculine. 13, 23, 43, 63 are neuter. 3 "neuters" numbers, with few exceptions. (83 or 93, because numbers beginning with 8 or 9 are feminized.) Any number with 3 or more digits that begin with 3 are masculine.
Am interesting property of 7?
For numbers 3+digits
an even amount of 7 is feminine, an odd amount is masculine. (exception, ANY numbers beginning with "17" are FEMININE. such as 170 000, 174, 965.....
