This is a headline template for Classical Nahuatl proper nouns. It formats the headline and also automatically categorises entries into Category:Classical Nahuatl proper nouns.
It can take up to two parameters, both of which are optional. The first one is unnamed, and should be supplied with the form marked with macra. The second one is also unnamed, and should be supplied with loc
for locatives (which is then categorised as such) or pl
for pluralia tantum (which is not categorised).
Note that these parameters are in a different order from {{nci-noun}}
.
