"Formal English" is used in professional settings or formal occasions, characterized by longer sentences, complex vocabulary, and adherence to grammar rules. "Informal English" is used in casual conversations or among friends, characterized by shorter sentences, simpler vocabulary, and more relaxed grammar.
Formal words are the words that are capitalized when used. Informal words are words that are not capitalized when used.
Formal language is characterized by the use of standard English, more complex sentence structures, infrequent use of personal pronouns, and lack of colloquial or slang terms.
Formal language, such as academic writing or legal documents, tends to have longer sentences and a wider range of vocabulary compared to informal language. This is because the goal of formal language is often precision, clarity, and specificity.
The writer likely chose their words and organized their sentences based on the tone of the letter. If the language used is formal, the writer probably selected words with a neutral or professional tone and structured the sentences in a more traditional manner. If the language is informal or casual, they may have opted for more relaxed wording and sentence structures.
An informal stream-of-consciousness style might include fragmented thoughts, random interjections, and a lack of traditional sentence structure. On the other hand, formal sentences with complex vocabulary might contain subordinate clauses, advanced syntax, and intricate phrasing. Sentences that do not conform to standard punctuation or grammar rules may feature intentional grammatical errors, unconventional word order, or experimental language choices.
