Saltigrade and Avahi

Two words from the 2025 Scripps National Spelling Bee prep materials: avahi, a term for a woolly lemur of Madagascar, and saltigrade, which describes spiders and other creatures that have feet and limbs adapted for leaping. Saltigrade is linguistically related to words in several Romance languages involving leaping, as well as the English word somersault. The -grade or “stepping” in saltigrade is related to tardigrade, which refers to hardy microscopic creatures so named because they move quite slowly. This is part of a complete episode.
