Sylvan
Etymology
From Latin "silva" ("wood, forest"); the Roman woodland god Silvanus took his name from the same root. The now-common spelling with "y" arose from a later, mistaken association with the Greek "hylē" ("wood, matter"). The word evokes places that are shaded and wooded.

Relating to or characteristic of woods and forests.
What it names
