Arpas (Spanish word) is the plural form of arpa (harp), the music instrument.

Answer 2

Rules to use an apostrophe

1. use it to mark omissions in contractions.....din't =did not; there's = there is

2. use it to form a plural of lower case letters and abreviations followed by periods.....his e's and o's

two v.p.'s

it is used so as not to cause confusion ...too many l's ,several A's;two plu's.

In your case, "Would it be Arpas or Arpa's?" remember that you are writen in Spanish not English.
