* σκέφτομαι (skéftomai): This is the most straightforward verb meaning "to think." To express "thinking about," you'd use it with a prepositional phrase. For example:
* Σκέφτομαι για σένα. (skéftomai gia séna) - I'm thinking about you. (This uses "για" - gia - meaning "about" or "for")
* Σκέφτομαι την κατάσταση. (skéftomai tin katástasi) - I'm thinking about the situation. (This uses "την" - tin - the accusative feminine singular article, indicating the object of the thought)
* λογαριάζω (logariázo): This verb means "to calculate," "to consider," or "to reckon." It implies a more deliberate and perhaps analytical form of thinking.
* Λογαριάζω τις επιλογές μου. (logariázo tis epilogés mou) - I'm thinking about (considering) my options.
* βρίσκομαι σε σκέψεις (vrískomai se sképseis): This phrase literally means "I'm in thoughts" and suggests being lost in thought or contemplation. It's a more evocative way of expressing being absorbed in thought.
* μελετάω (meletáo): This means "to study" or "to contemplate," and is appropriate when the thinking is focused and intense, often about a specific subject.
The best choice will depend on the context. For a general "thinking about," `σκέφτομαι για...` (skéftomai gia...) is usually a safe bet.
