What is the Greek word for Aspire?

There isn't one single perfect Greek word for "aspire," as the meaning depends on the nuance. However, several words could be used depending on the context:

* ὀρέγομαι (oregomai): This verb means "to reach out for," "to strive for," or "to long for." It carries a sense of reaching towards something desired, and is probably the closest single word.

* ἐπιθυμέω (epithyméo): This means "to desire," "to yearn for," or "to long for." It emphasizes the desire itself more than the active striving.

* Words incorporating the concept of ambition (φιλοδοξία - *philodoxia*) or ambition's aim (στόχος - *stochos*) could also be used in a phrase to convey the meaning of "aspire."

The best choice would depend on the specific context of how "aspire" is used in the sentence.
