Here's why:
* Meaning: "Influential" means "having a great influence on someone or something." It's already implying a high level of influence.
* Usage: You wouldn't say "more influential" or "most influential" because it sounds redundant. Instead, you would use adverbs like "more" or "most" to modify the noun it describes:
* Example: "She is a more influential figure in the company than her boss."
* Example: "He is the most influential leader in the country."
You can also use other words to convey different levels of influence:
* Less influential: To indicate a lower level of influence.
* Highly influential: To emphasize a strong level of influence.
* Extremely influential: To suggest a very significant impact.
Ultimately, the best way to express different levels of influence depends on the context and the desired emphasis.
