Hoppip may derive from hop, hip-hop, or hippity-hop, indicating that it jumps or flies through the air; pip, a type of seed; or pipsqueak. The names of all stages of its evolutionary line are based on the phrase, "Just a hop, skip, and a jump away."
Hanecco may be any combination of 葉 ha (leaf), 跳ねる haneru (to jump or hop), or 羽 hane (wing), and 根っ子 nekko (root). Its name may also be a pun on 猫 neko (cat), given its cat-like ears and tail.
