The ground covered is often a linear extent with or without specific starting and ending points:

• The bird flew over the building. 001

• The sun traveled across the sky. 002

• Hot water is running through the pipes. 003

• They dance in a circle. 015

It can also be a waypoint/something that must be passed or encircled.

• We flew to Rome via Paris. 004

• I go by that coffee shop every morning. 005

• The earth has completed another orbit around the sun. 006

If this is a portal in the boundary of a container, it is often construed as Source, Goal, or Locus:

• The bird flew in the window. (Path↝Locus) 007

• The bird flew out the window. (Path↝Source) 008

• A cool breeze blew into the window. (Path↝Goal) 009

However, if the entirety of the motion event is simply located, Locus applies:

• The bird was flying in the house. [The flying took place in the house.] (Locus) 013

• They were running on the street. [The running took place on the street.] (Locus) 014

The prepositions around and throughout can mark a region in which motion that follows an aimless or complex trajectory is contained. Construal is used for these, whether or not the region is explicit:

• Locus↝Path:

  • The kids ran around. 010

  • The kids ran around/throughout the kitchen. 011

  • The kids ran around in the kitchen. 012
