1. Clarity and Precision:
* Idioms are often ambiguous: Their meaning can be difficult to decipher, especially for non-native speakers or those unfamiliar with the specific cultural context. This can lead to misinterpretations and confusion.
* Slang is constantly evolving: It has a limited lifespan and can quickly become outdated, making it difficult to understand for audiences who aren't up-to-date on the latest trends.
* Formal language prioritizes clarity and precision: It aims to convey information accurately and effectively, without relying on figurative language that can be open to interpretation.
2. Professionalism and Authority:
* Idioms and slang can be perceived as informal or casual: They are associated with everyday speech and can detract from the seriousness and authority of formal writing or speaking.
* Formal contexts require a higher level of professionalism: Using formal language demonstrates respect for the audience and the occasion.
3. Audience Consideration:
* Formal language is designed for a wide audience: It needs to be accessible and understandable to individuals from various backgrounds, regardless of their familiarity with specific idioms or slang.
* Formal language is often used in academic, legal, or professional settings: These settings demand a high level of objectivity and neutrality, which is best achieved by avoiding informal language.
4. Cultural Sensitivity:
* Idioms and slang can be culturally specific: They may not translate well across different cultures, and their use could be misinterpreted or even offensive.
* Formal language strives for universality and inclusivity: It aims to be understood and respected by everyone, regardless of their cultural background.
In short, idioms and slang are generally avoided in formal language because they can hinder clarity, professionalism, and cultural sensitivity. Formal language aims to be clear, precise, and accessible to a wide audience, and idioms and slang often fall short of these goals.
