Chattat
Chattat (חַטָּאת)
Meaning: While also translated as "sin," "chattat" more specifically refers to a sin offering or a purification offering.
Usage: In the Torah, a "chattat" is a specific sacrifice brought to atone for unintentional sins, emphasizing forgiveness and purification. The type of animal required for the offering depends on who committed the sin, such as the high priest or the community.
Connection to Chet: The Hebrew word for "sin offering" (chattat) is nearly identical to the word for "sin" (chata), suggesting a strong link between the act of sin and the need for atonement and purification.
