Etymology: The most surprising thing about "sympatry" is how far its meaning has drifted from its parts. Its Greek ingredients are "sún", meaning "with" or "together", and "patrís", meaning "fatherland" or homeland. Put together, they suggest people sharing a country, and the word's biological sense grew from the same idea of shared territory: species that live in the same place rather than being separated by distance or geography. The "patrís" element is the one that gives the word its unusual flavour. Ancient Greek used it for ancestral land and native home, so the modern term takes a word about citizenship and belonging and applies it to animals and plants that happen to occupy the same ground. The contrast term "allopatry" follows the same pattern, with "állos" meaning "other", so species living in separate places are "other-homeland" populations.
