Question

Why text messaging caused the deterioration of proper English usage?

Answer 1

Texting shortens words and doesn't use proper puncuation. Like "tht" or "l8r"

Answer 2

Because there is limited space, words are shortened to make room. Also, to save time, capital letters and punctuation are almost non-existent in a text.

Answer 3

In order to save time and fit more words into a message, words were abbreviated. This has become so common that most people text this way. It has become a habit to most people.
