Here's why:
* No verb form: There is no grammatical verb form of "eager" in English.
* Meaning mismatch: The meaning of "eager" doesn't readily translate to a verb action. It describes a state of mind or feeling.
Instead of using "eager" as a verb, you can use:
* "To be eager": This is the most common way to express the concept. Example: "She is eager to learn."
* "To eagerly await": This describes the action of waiting with anticipation. Example: "He eagerly awaited her arrival."
* "To anticipate": This implies looking forward to something. Example: "They anticipated the release of the new album."
* "To look forward to": This expresses excitement about a future event. Example: "I'm looking forward to seeing you again."
Remember to choose the verb that best fits the context and meaning you want to convey.
