The letter "ד" (Daled) is the fourth letter of the Hebrew alphabet. It has a numerical value of four and is often associated with the word "דלת" (delet), meaning "door." In Hebrew, letters can also represent sounds, and "ד" produces the "d" sound, similar to the English letter "D." In Jewish tradition, "ד" is significant in various religious texts and prayers. It appears in the names of important figures, such as David, the second king of Israel. The shape of the letter is distinctive, resembling a small rectangle with a protruding line, which contributes to its unique identity in the Hebrew script.
