Phetoho ho tloha phaepheng e phaphametseng ho ya phaepheng e ka tlasa metsi e phethahala ka ho sebedisa monyetla wa ho tenyetseha ho hotle le ho tiya ho itekanetseng ha Phaephe e Phaphametseng e Tapered le Phaephe e fetotsweng ke leralla. Sekema sa moralo se amohetsweng ke: Phaephe e phaphametseng + Phaephe e Phaphametseng e Tapered + Phaephe e fetotsweng ke leralla + Phaephe ya Tshepe + Phaephe e fetotsweng ke leralla + Phaephe ya ka Tlas'a Metsi. Nakong ya tshebediso, sete ya phaephe e hlahisa sebopeho se kobehileng sa "s", mme e ka fetola boemo ba yona ba ho kobeha ho ikamahanya le phapang ya boemo ba metsi e bakwang ke maqhubu a nyolohang le maqhubu a theohang, ha e ntse e netefatsa hore mola wa phaephe ha o sitiswe. Ena ke moralo o atlehileng wa moralo o sebedisitsweng Chaena. Mererong ea ho cheka metsi ho tsoa Chaena, ho na le moralo o mong oa liphaephe bakeng sa phetoho ho tloha phaepheng e phaphametseng ho ea phaepheng e ka tlas'a metsi, e leng: Phaephe e phaphametseng + Phaephe e Felletseng e Phaphametseng (SG 2.1) + Phaephe e Felletseng e Phaphametseng (SG 1.8) + Phaephe e Felletseng e Phaphametseng (SG 1.6) + Phaephe e Felletseng e Phaphametseng (SG 1.2) + Phaephe e se nang liphaephe + Phaephe e ka Tlas'a Metsi, e leng morero o sebetsang.
