fax
/ˈfaɡs/ · B2 · noun · m
facsimile
📠 Sounds like English fax, said 'fahks': same word, same machine, masculine: el fax
Spanish borrowed fax directly from English, which shortened facsimile (Latin fac simile, 'make similar'). The plural stays the same: los fax. Just remember the gender: el fax, not la fax.
