sylvan

Etymology

Borrowed from Medieval Latin sylvanus, possibly via Middle French sylvain, from Latin silvanus, cognate with Latin Silvānus (“Roman god of the woods”), from silva (“forest”), from Proto-Indo-European *sel-, *swel- (“beam, board, frame, threshold”). The ⟨y⟩ in sylvanus and its descendants is due to influence from Ancient Greek ῡ̔́λη (hū́lē, “wood, matter”), transliterated in the Latin style as hyle. Analysable as sylva (“silva”) + -an.
