Letter D
The letter D symbolizes a linear jump counting, always with the same digit, forward and backward, from one digit to another, within a number with a couple of digits.
Generally combined with the letter A or the letter E to indicate by which side (in feminine or in masculine ) of the number you must jump from one digit to another.
An example:
For the number of two digits ... 26, the second word, the third word, the fourth word, the fifth word and the sixth word will be selected (counting forward in masculine). And back (counting on the same backward twist in feminine) the sixth word, the fifth word, the fourth word, the third word and the second word. And so successively.
For the number ... 51 you will select (counting forward in feminine) the fifth word, the fourth word, the third word, the second word and the first word. And back (counting on the same digit back in masculine) the first word, the second word, the third word, the fourth word and the fifth word. And so successively.
For the number ... 33 the third word will be selected and, again, the third word. And so successively
