The sociolect emerged among the Bulgarian masons in southwestern Macedonia, adjacent to the Albanian lands. As a result, it includes a large number of Albanian loanwords, e.g. бука buka, "bread", from bukё; гяхта gyahta, "cheese", from djathë; мерам meram, "to take", from marr. There are much fewer loans from Greek (e.g. лашма lashma, "mud", from λάσπη laspi; карекла karekla, "chair", from καρέκλα karékla) and Turkish (e.g. пиринч pirinch, "rice", from pirinç; сакал sakal, "beard", from sakal).[3] Later, the language spread through migration to northeastern Macedonia (the region of Gotse Delchev), the Rhodope Mountains around Smolyan, and the areas of Asenovgrad, Kazanlak and the sub-Balkan valleys.[2]
Although loanwords often remained semantically unchanged, the Bulgarian vocabulary in the sociolect was substituted with native metaphors, metonyms and words from different roots, so as to conceal the true meaning to outsiders, e.g. мокра mokra ("wet", fem.) for вода voda, "water"; гледач gledach ("looker") for око oko, "eye", обло oblo ("round", neut.) for яйце yaytse, "egg".[3] The lexis of Meshterski included not only professional terms and basic vocabulary, but also other words, including religious terms, such as Светлив Svetliv, "Luminous", referring to God or a saint.[4]
Meshterski also spread to other social areas: it was borrowed by tinsmiths in at least one village in the Rhodopes, although with a much reduced vocabulary and renamed to Ganamarski.[5] Albanian words mediated through Meshterski have also entered informal Bulgarian; these included кекав kekav, "weak, sickly" (from keq); кинти kinti, "money, dough" (from qind, "hundred"), скивам skivam, "to see, to take a look" (from shqyrtoj), келеш kelesh, "squirt, mangy fellow" (from qelesh).[6]
