Write in a formal, persuasive, and descriptive manner

Recognise the importance of audience: Stay mindful of your readers and use a language level appropriate for them. Formal writing often targets an educated audience.
Stick to third person perspective: ‘He’, ‘She’, ‘It’, and ‘They’ are generally more proper than first person pronouns like ‘I’ and ‘You’.
Keep abbreviations and contractions (like can’t, won’t, etc.) to a minimum - their use can make your writing seem informal.
Pay attention to spelling, grammar, and punctuation. Errors can damage the formal tone.

Be sure about your standpoint: Clearly define the point you’re arguing for or against. It will become the backbone of your persuasive writing.
Use evidence to support your arguments: Statistics, quotes and factual information help establish your arguments and make them more compelling.
Leverage the power of emotive language: Words that evoke emotions in readers can be extremely effective in persuading them to your viewpoint.
Apply rhetorical questions: These can engage your readers and lead them to consider your argument seriously.

Make use of sensory description: Draw on the five senses to create vivid imagery and immerse your reader in your writing.
Prioritise showing, not telling: Instead of directly telling the reader how something is, use your words to paint a picture that conveys the same idea.
Use strong adjectives to enhance the depth of your descriptions and make them more compelling.
Incorporating similes and metaphors can help to add a creative flair to your descriptions, and elaborate specific details further.
