English essay, why we spell phonetically?

[Cameron]

Hi there,

I'm currently doing GCSE English, I was writing an essay/ assessment today that goes towards my final grade and well I got a little stuck. Luckily I have tomorrow to finish it. The whole idea of the essay is to compare the English language on different types of social media and how it differs between each one. I was beginning to write a paragraph on how we spell phonetically and how we spell things depending upon how we say them. For example I was writing about the fact I used 'ova' instead of 'over' when texting. I need atleast three reasons as to why we spell phonetically when texting. Please help me!

Thank you in advance!
