The gender of adjectives is marked with the form tags `m' or `f'. Invariable adjectives do not take any gender tag.
In Catalan, there are no neuter adjectives. A gender value c (`common') is needed for the gender (and sometimes gender and number) of invariable adjectives, in the same way as the L2b value proposed for Italian and Spanish.
