• Writing in the first person
Unlike academic writing, casual writing allows the writer to write in the first person, and they can refer to themselves as 'I' or 'me'.
• Grammar and spelling
Casual writing allows the writer to be less fussy with grammar and spelling, and in some cases the spellings and grammar are deliberately incorrect, depending on the subject matter. Punctuation use is also relaxed although the piece of writing should still be legible to the reader.
• Informal writing
The writer can refer to the person who is going to read the article by name or as "You". This is a less formal way of writing than academic writing, in which the person to read the article or letter is referred to in the third person.
• Writing as people speak
Casual writing is often written as though the text is being spoken and is therefore grammatically incorrect. This is frowned upon when writing for the internet, but is down to personal preference when writing personal letters and e-mails.
• Differences between casual and academic writing
The major differences between casual writing and academic writing are tone, style and purpose. Academic writing requires proper research and structure, whereas casual writing can contain the personal opinions of the writer and is generally more relaxed.
