Young Brunette Girl With A White Top And A Skirt With Suspenders Reveals On The Rug In The Apple Grove

The primary meaning of "grove" is simply a group of trees that grow close together, generally without many bushes or other plants underneath. It is an old word in English, existing more than 1,000 years ago, but it is of unknown origin.
Naturally occurring groves are typically small, perhaps a few acres at most. Orchards, by contrast, may be small or very large indeed, such as the apple orchards in Washington state; but to complicate matters, crops of oranges (as in Florida) are usually known as orange groves, and they too can be enormous.
