**Explanation:**

When communicating with others, it is essential to prioritize clarity for effective understanding and interpretation of information. Avoiding complex word sentences and technical jargon helps in achieving this goal. Here's a detailed explanation of why clarity is important:

1. **Enhances comprehension**: Using simple and clear language ensures that the message is easily understood by a wider audience. Complex word sentences and technical jargon may hinder comprehension, especially for individuals who are not familiar with the specific terminology.

2. **Fosters inclusivity**: By avoiding complex word sentences and technical jargon, communication becomes more inclusive. It allows individuals from diverse backgrounds and varying levels of expertise to access and engage with the information being conveyed. Clarity promotes effective communication across different demographics.

3. **Reduces ambiguity**: Complex word sentences and technical jargon often introduce ambiguity into communication. Ambiguity can lead to misunderstandings and misinterpretations of the intended message. Clear and concise language helps to eliminate confusion and promotes accurate understanding.

4. **Simplifies complex concepts**: In situations where complex concepts need to be explained, using clear and simple language helps in breaking down those concepts into more easily digestible pieces of information. This enables the audience to grasp the main ideas without getting overwhelmed by technical jargon.

5. **Improves overall communication**: When complex word sentences and technical jargon are avoided, the overall quality of communication improves. It becomes easier for the audience to engage with the content, ask relevant questions, and provide meaningful feedback. Clarity facilitates effective communication, leading to better outcomes.

In conclusion, choosing clarity as a guiding principle in communication involves avoiding the use of complex word sentences and technical jargon. By doing so, information becomes more accessible, inclusive, and easily comprehensible to a wider audience.
