Several instances of popular etymology are attested from ancient authors. Thus, the Greeks most often associated Apollo's name with the Greek verb ἀπόλλυμι (apollymi), "to destroy". Plato in Cratylus connects the name with ἀπόλυσις (apolysis), "redemption", with ἀπόλουσις (apolousis), "purification", and with ἁπλοῦν ([h]aploun), "simple", in particular in reference to the Thessalian form of the name, Ἄπλουν, and finally with Ἀειβάλλων (aeiballon), "ever-shooting". Hesychius connects the name Apollo with the Doric ἀπέλλα (apella), which means "assembly", so that Apollo would be the god of political life, and he also gives the explanation σηκός (sekos), "fold", in which case Apollo would be the god of flocks and herds. In the Ancient Macedonian language πέλλα (pella) means "stone," and some toponyms may be derived from this word: Πέλλα (Pella, the capital of Ancient Macedonia) and Πελλήνη (Pellēnē/Pallene).
