The plural of waltz is <em>waltzes</em>.
To form the plural of a regular noun we add an -s at the end of the singular word.
- Brother → brothers
- sister → sisters
There are some exceptions to this general rule, considering the ending of the singular noun.
If the noun ends in -s, -ss, -ch, -sh, -x or- z, we add -es at the end of the singular word to form the plural:
- Ibis → ibises
- witness → witnesses
- church → churches
- fish → fishes
- mix → mixes
- blitz → blitzes
In the case of waltz, we add -es to form the plural <em>waltzes</em> because the singular noun ends in -z.
