Book excerpt: Harsusi is a South Semitic language spoken in the Jiddat al-Harasis area in Oman by some 500 to 1500 speakers. It is strongly related to Mehri, a language spoken in Oman and Yemen, with some 100000 speakers. There is very little documentation on Harsusi. The only work available was the H.arsusi Lexicon by T.M. Johnstone (d. 1983), who did fieldwork not only on Harsusi but on all six South Semitic languages in the early seventies of the 20th century.The texts on which T.M. Johnstone based his Harsusi Lexicon are published in this book. Or to put it differently: with these texts Johnstone's Harsusi Lexicon comes to life.
