EDIT Meaning De (Д, д) is a letter of the Cyrillic alphabet. It represents /d/ a voiced dental plosive except word-finally and before voiceless consonants, when it represents a voiceless [t] and before any palatalizing vowel, when it represents /dʲ/.
It arose from the Greek letter delta; the major graphic difference with its Greek equivalent lies in the two \"feet\" below the lower corners of Greek letter delta. Like El, it has two typographical variants: one where its top is square, and one where it is pointed (like delta).
The handwritten form of capital letter De appears like Latin D as the printed version shown here is not comfortable enough to be written quickly. The handwritten lowercase letter looks a bit like a Latin g and it is joined to a following letter by its tail. In cursive type, the lowercase form looks more like the lowercase Latin d: Д, д.
