Depending on the local dialects and countries that speaks the language differently, the Portuguese language can have approximately 31-37 phenomes, whereas the Spanish language has about 24-26 phenomes. Thus, the simple answer is yes, the Spanish language has fewer phenomes than the Portuguese language. If you want a break down of the categories of phenomes (example: short vowels, consonant sounds, etc.), you can find a list on the sources below. I hope that helps! Good luck - Alcir
