Short Answer 
Informal English is used in relaxed settings with casual phrases and slang, while formal English is appropriate for serious contexts, focusing on proper structure and grammar. Identifying casual language, such as “gonna grab a bite” versus the formal “going to have dinner,” helps understand the suitability of each style in different situations.
Understanding Informal and Formal English
Informal English refers to the way we communicate in relaxed situations, such as with friends or family. It tends to be more conversational, incorporating slang and casual phrases. On the other hand, formal English is utilized in serious contexts, such as literature or professional settings, focusing on structure and grammar.
Identifying Casual Language
To identify casual expressions, look for phrases that are commonly used in speech. For example, “when I was growing up” reflects a casual tone. In contrast, phrases like “when I was a child” demonstrate a more formal usage. Recognizing these differences can help in understanding the context in which each type is appropriate.
Exploring Example Phrases
Here are some examples to illustrate the differences between informal and formal English:
- Informal: “I’m gonna grab a bite.”
- Formal: “I am going to have dinner.”
- Informal: “He’s cool.”
- Formal: “He is impressive.”
Recognizing these alternatives will enhance your language skills in various contexts.
