I understand the grammar of 'yo como' and 'tú comes'. That's vey regular.

But 'yo tengo' and 'tú tienes' don't seem to be related to each other. Why does the prefix change instead of just the suffix?

  • The verb tener has an irregular conjugation, that's why. – Capie Feb 16 at 11:27
  • let's say that tener is an old verb that comes from latin, very used every year. This means, more use by the people means more changes along the years, coming as an irregular verb. – Iria Feb 17 at 10:35
