What is the greek definition for egocentric?

There isn't a single, established Greek word that perfectly translates to "egocentric." The concept itself is a relatively modern psychological one. However, you could construct a phrase using Greek roots to approximate the meaning.

A possible rendering would involve combining words like:

* ἐγώ (ego): "I"

* κέντρον (kentron): "center," "point"

You could then create something like ἐγώκεντρος (egōkentron), meaning literally "I-centered." This would be understood by someone familiar with Greek roots, but it's not a classical or established word. Other combinations focusing on "self" and "center" are possible, but all would be neologisms (newly coined words).

Therefore, while there's no direct Greek equivalent, ἐγώκεντρος (egōkentron) serves as a reasonable approximation built from existing Greek roots.
