OK I concede. Mouse IS from lahak via the Latin mus – from the word MAOZ, meaning fortress!
Roman soldiers found it so easy to penetrate the shlimazeldige fortresses built by the baryonim, sicarii etc that they likened them to mice. Others say that mouse comes from maoz because getting rid of mice is as difficult as penetrating a fortress.
Anyone who believes that can pay me $19.95 a month for the rest of their lives so I can have someone recite kapitel 256 at the kever of Charles Ponzi for a segulah against mice.
