Por que escribimos "e" el lugar de "y"?

In Spanish the rule has to do with the ease of pronunciation or clash of sounds. If the second word you are adding stars with an I or Hi, then "y" has to be replaced by "e" or just switch the two words to avoid a phonetic clash. Example. Sé hablar español e inglés, or Sé hablar ingles y español. This also applies when you are using "o" (or). Te va a salir mal de una u otra forma. Note that the "o" was replaced by an "u" to avoid a phonetic clash.
If the word following the conjunction "y" begins with "i" or "hi" and has the ee sound of the "y" then you substitute "e" for "y". It is just a pronunciation workaround like "el" agua.
In front of the vowels "e" and "i" one uses 'e' instead of 'y', just to separate the similar sounds.
