==Proper Spelling of Kalir's name== 

 Eleazer (sic!) is a non-existent name. There is Eleazar (or more precisely El'azar) and Eliezer (or more precisely Eli'ezer). In the former case the final syllable is stressed, in the latter - the penultimate one. Eleazar berabbi (ben rabbi) Kalir (or Qallir) is the accepted spelling of the poet's name. 

 == "Ma'adanei Yom Tov"? == 

 Could somebody please verify and expand this edit: what is Rosh to Brochos Siman 21? Is "Ma'adanei Yom Tov" mentioned by Yom-Tov Lipmann Heller, as I see in his Hebrew entry?
