Two things to keep in mind when you're deciding whether to use formal or informal English are the occasion and the audience.
Who are you talking to? Where are you having the conversation? If it is a book, who is the intended audience?
Consider the audience you are addressing and the level of formality that is appropriate for the situation. Additionally, be mindful of the tone and style you want to convey through your choice of language.
Figures of speech can be used in both formal and informal English. They are often used to add depth and creativity to language, whether in professional writing or everyday conversation.
You should consider the expectations of the people to whom you are talking (or for whom you are writing), and also check your horoscope for the day and see if the astrological influences favor informal or formal English.
occasion and audience
Formal: Goeiedag ----> English equivalent: Goodday Informal: Hoi ----> English equivalent: Hi
Formal English is the English written in works like essays, where it's a standardized, formal way to write it, but informal English is what I'm writing in right now, a loose, not very structured way of writing.
Please = Alstublieft (formal) and alsjeblieft (informal) Thank you = dank u wel (formal) and dankjewel (informal) Goodbye = tot ziens / dag (formal) and doei (informal)
occasion and audience
like the Russian , English is a formal table style .. but it can be formal or informal depending on the diner if he\she wants to.
It means "You (informal) or you (formal)"
Formal English is used in professional settings, academic writing, or formal speeches, while informal English is used in casual conversations, texts, or social media. Formal English follows strict grammar rules and uses sophisticated vocabulary, while informal English is more relaxed with slang, contractions, and colloquial expressions.
very informal: Hey informal: Hi more formal: Hello formal: Good morning Good afternoon Good evening
