Brda dag phye ma leb kyi rtsa ʼgrel dang Sum rtags kyi dris lan

Commentary and exegis by Geden Tashi (Dge-ʼdun-bkra-shis, born in 1970 in Rebgong) on the Tibetan orthographical grammar "Sgra rig gnam ʼphang gcod byed Brda dag phye ma leb kyi gshog rlabs" written in verse by Dpyi-sa Blo-gros-rgya-mtsho (1890-1959) from Rtse-khog. The commentary is based on oral instruction by the author's lama teachers and is comprised primarily of a glossary with explanation of terms in the root text (pages 1-50), which precedes the main text. Also includes two short works in question-answer format as commentary on two traditional orthographical grammars, the Sum-cu-ba (pages 210-265) and the Rtags-ʼjug (pages 266-300)
