What language is the Etruscan language, spoken by the ancient Etruscans in Italy?

Several Latin words are believed to have been borrowed from the Etruscan language, though often indirectly via other intermediate sources such as Umbrian or Sabellian languages. Examples include Etruscan "raχs" (meaning head), from which the Latin "rex" (meaning king) was derived, and Etruscan “c????ruzle” (meaning dwarf), which may have become Latin “curculus” and ultimately entered Italian as “corbello” (meaning small basket). Nevertheless, the number of Etruscan loanwords in Latin is relatively small compared to the extensive influence of Greek.
