Jan 23, 2016 - Mapa is masculine: http://www.spanishdict.com/translate/map It's one of those (confusing) Spanish words that look feminine but are masculine, for various etymological (word history) reasons. If you come across a Spanish noun ending in -ma, -pa, or -te, be sure to double check the gender. :-)
Also, please check the whole thread to see if your question has already been answered.
Mapa is the only masculine -pa noun I have found, except for el papa/the pope with natural gender. Hence -pa words are not much to worry about.
The gender however is very peculiar. It comes from the Latin mappa which is feminine just as most -a nouns in Spanish. So why did they change the gender?
this is what I put but the correct answer according to Duo was the map's fifteen dollars, da!
