Here's a breakdown:
* περι- (peri-) means "around" or "about"
* πλανώ (planó) means "to wander"
* -μενος (-menos) is the present participle ending
So, περιπλανώμενος literally means "one who is wandering around".
There are other words that can be used for wanderer in Greek, depending on the context, such as:
* αδέσποτος (adespotos) - homeless, stray
* νομάς (nomás) - nomad
* ταξιδιώτης (taxidiótis) - traveler
* περιηγητής (perigiítis) - explorer
The best word to use will depend on the specific context and the nuances you want to convey.
