* Simple Sentence Structures: Informal English tends to use shorter, simpler sentences than formal English. Complex grammatical structures are less common.
* Contractions: Words are often contracted (e.g., "can't," "won't," "it's").
* Phrasal Verbs: Common use of phrasal verbs (e.g., "look up," "put off," "get along").
* Colloquialisms and Slang: Informal English frequently employs colloquialisms (words and phrases used in everyday speech) and slang (informal language particular to a group or time). These can vary widely by region and social group.
* Figurative Language: Metaphors, similes, and idioms are often used to add color and expressiveness.
* Interjections: Words or phrases that express strong emotion (e.g., "Wow!", "Oh my god!", "Seriously?") are common.
* Personal Pronouns: First and second person pronouns ("I," "you," "we") are used more freely.
* Less Emphasis on Precise Vocabulary: While formal English emphasizes accuracy and precision in word choice, informal English is more tolerant of imprecise or vague language.
* Abbreviations and Acronyms: Common use of abbreviations and acronyms (e.g., "LOL," "OMG," "FYI").
* Sentence Fragments: Incomplete sentences are acceptable in informal contexts.
Examples contrasting formal and informal English:
* Formal: "The individuals proceeded to the designated location."
* Informal: "They went there."
* Formal: "It is imperative that you submit the assignment by the deadline."
* Informal: "You gotta hand it in on time."
* Formal: "I would be grateful if you could provide assistance."
* Informal: "Could you help me out?"
Essentially, informal English is the language of everyday life, whereas formal English is reserved for more serious, professional, or academic settings. The appropriateness of using informal English depends entirely on the context.
