Adverbs of place
Sound symbols
Except for a few words (here, there, somewhere, etc.), adverbial expressions that answer the question where? are prepositional phrases (to the sea, in the house, under the tree, etc.). These words and phrases occur normally in final position. For special emphasis or contrast, they may sometimes occur initially.
We ate breakfast outside.
He was sitting at his desk.
She was wearing a large hat on her head.
On her head she was wearing a large hat.
Adverbial expressions of place occur initially in sentences of this type:
In front of the house is a large tree.
On his desk was an old-fashioned lamp.
These sentences are equivalent to sentences beginning with dummy there:
There is a large tree in front of the house.
