Noun
alfil (plural alfils)
(chess) A fairy piece that moves two squares diagonally, leaping over any intermediary pieces.
The Spanish alfil is simply a loanword of the Persian term, without any other meaning; while the Italian form, interestingly enough, became alfiere —an already existing Germanic- or Arabian-derived word for standard-bearer. Source: Internet
Murray 1913, p.344 Derivatives of alfil survive in the languages of the two countries where chess were first introduced within Western Europe—Italian (alfiere) and Spanish (alfil). Source: Internet
