Why is H silent in Portuguese and Spanish?

Question

Why is H silent in Portuguese and Spanish?

Answer 1

As far as I know linguistics (I've got MA in general linguistics), there is no "why" in language! But, since you can observe the same phenomenon more or less in all Latin-based languages: Spanish, Portuguese, Italian, French, even in spoken English (and most probably in Latin), that could 'ave an 'istorical answer!

Answer 2

it just is    it's silent in french too  :-)

Answer 3

because in spanish they dont really use the H they use J instead like Jarritos the drink its written Jarritos but its pronounced Harritos.

Hope this helped you understand
