Why are there so many 4-tuples of portuguese nouns of the form:
[ C(C)oC(C)o, C(C)aC(C)o, C(C)oC(C)a, C(C)aC(C)a ]
in which all 4 words are legit portuguese nouns?
For example, below are all legit portuguese nouns:
- coco/coca/caco/caca
- colo/cola/calo/cala
- golo/gola/galo/gala
- goto/gota/gato/gata
- molho/molha/malho/malha
- moto/mota/mato/mata
- posto/posta/pasto/pasta
- soco/soca/saco/saca
- troço/troça/traço/traça
This is very confusing and easy to messe them up. How to learn their differences by heart and avoid messing up?
