Category talk:Portuguese nouns with irregular gender

Regularity of subcategories
Hi. I noticed you created this category. I get the impression that you are simply categorizing as irregular every noun that ends in -a but is masculine. I don't that makes much sense. For instance, the overwhelming majority of Portuguese words ending in -ema are masculine (e.g.: tema, lema, problema, sistema, cinema). The only counterexamples I can think are gema, algema, and alfazema. I believe that such category of words shouldn't be labelled as irregular since a gender rule can be clearly established. - Sarilho1 (talk) 10:53, 29 September 2022 (UTC)
