The tags used by the Catalan tagger are mostly based on Freeling.
See: https://freeling-user-manual.readthedocs.io/en/latest/tagsets/tagset-ca/

For example, "cap" will be tagged with these strings:

wordform lemma postag 

cap cabre VMIP1S0Z
cap cabre VMIP3S00
cap cabre VMM02S00
cap cap DI0CS0
cap cap NCCS000
cap cap PI0CS000
cap cap SPS00
cap capar VMIP1S0B

to see how words are tagged by LanguageTool.
