were at home in the woodlands, and mostly settled in the area of Beleriand known as Ossiriand. They were elusive and wary of strangers, and a human or a Noldorin or Sindarin elf could wander through Ossiriand for days and never encounter one of them.
It is unclear whether the Sylvan Elves of the Third Age (who make up the bulk of the elves in the Hobbit and Lord of the Rings) are Laiquendi, but it seems likely since they have similar habits (they are elusive and distrust strangers), have their own language and live in areas similar to Ossiriand (forests and wooded dells), including Lindon, which is basically Ossiriand in the Third Age. Thus, the elves of the Woodland Realm such as Thranduil the Elvenking and Legolas, the non-Sindarin elves of Lorien and the elves of Rivendell are probably Laiquendi.
Of all Tolkien’s Elves, the Laiquendi most closely resemble the standard Elf of fantasy literature and RPG’s.
