More than 30 years ago Andrzej Zaborski (1983; 1987 {1983}) collected and analyzed all Cushitic and Omotic numerals, which were described in his time, and tried to analyze their internal structure. His two pioneering studies stimulated the present attempt to collect all available relevant data about Cushitic numerals and to analyze them in both genetic (Afroasiatic) and areal (Omotic, Ethio-Semitic and Nilo-Saharan) perspectives, all at the contemporary level of our knowledge. With respect to the long mutual interference between various groups of Cushitic and Omotic languages, it is necessary to study the numerals in both the language families together. The presented material is organized in agreement with the genetic classification of these languages. On the basis of concrete forms in individual languages the protoforms in partial groups are reconstructed, if it is possible, and these partial protoforms of numerals in the daughter protolanguages are finally compared to determine the inherited forms. The common cognates are finally compared with parallels in other Afroasiatic branches, if they exist, or with counterparts in Ethio-Semitic or Nilo-Saharan languages, if they could be borrowed from or adapted into the Cushitic or Omotic languages.
In the present contribution the Beja botanical terminology is analyzed from the point of view of semantic motivation. The study is limited only to the unborrowed part of the botanical lexicon (with some exceptions), together 76 terms. First 51 terms are etymologized with help of external comparisons with probable cognates in other Cushitic or Afroasiatic languages. The last 25 terms are understandable from the point of view of internal etymology and their semantic motivation is more transparent than in the preceding cases.
The contribution summarises the Beja lexicon connected with natural phenomena, including astronomical, temporal, and geographical terminology. Every lexeme is documented in available sources and etymologized in areal or genealogical perspectives. In the case of borrowings, the ambition is to trace primary donor-languages, usually Arabic or Ethio-Semitic, sometimes Nilo-Saharan. The inherited lexemes are identified, if no convincing donors were determined, while there are promising comparanda in other Cushitic, Omotic or other Afroasiatic branches.
