The word "Talmud" means primarily "study" or "Learning" and is employed in various senses. One refers to the opinions and teachings which disciples acquire from their predecessors in order to expound and explain them (Seder Tonna'im ve-Amora'im cf. Rashi to Suk. 28b ; BM 32 a-b, et al.)
It Bears meaning for instance in the statement "Be heedful in Talmud for unwitting error in Talmud is accouted a willful transgression" (Avot 4:13)
Another sense comprises the whole body of one's learning ; e.g., "He From whom one has acquired the greater part of his Talmud is to be regarded as one's teacher" (BM 33a).
A third meaning is in the technical phrase Talmud lomar, which is used to indicate a teaching derived from the
exegesis of a biblical text. The word "Talmud" is most commonly used, however, to denote the body of teaching which comprises the commentary and discussions of the Amoraim on the Mishnah of R. Judah ha-Nasi
