Two of the best-attested genres of halakhic literature are (in English) referred to as codes and responsa. The former includes the Mishne Torah, the Arba'ah Turim, the Levush and the Shulchan Arukh (amongst others), while the latter includes collections like Shaagat Aryeh, Iggrot Moshe, etc. While responsa is referred to in Hebrew as She'alot uTeshuvot, or SHuT (שו״ת = שאלות ותשובות), it occurs to me that I've never seen the former so designated in Hebrew text.
Is there a Hebrew name for the genre of literature that is termed "Codes" in English?
