magellanic

The word 'Magellanic' is a modern English formation, directly derived from the name of the 16th-century Portuguese explorer Ferdinand Magellan. By appending the productive English adjectival suffix '-ic', meaning 'of or pertaining to', the word transforms the proper noun into an adjective. This suffix, originating from the Latin '-icus' and Greek '-ikos', is commonly used to form adjectives from names, as in 'Byzantine' or 'Shakespearean'. Consequently, 'Magellanic' serves specifically to denote a direct association with Magellan, most famously seen in celestial features named after his expedition, such as the Magellanic Clouds, two irregular dwarf galaxies visible in the Southern Hemisphere.

This is a proper adjective formed from the name "Magellan" (the surname of the explorer Ferdinand Magellan) with the addition of the adjectival suffix "-ic". The name "Magellan" itself is of uncertain origin but is the Latinized form of the Portuguese name "Magalhães".
