Explanation:
Transitions help the reader to progress from one idea to the next. They prevent sudden mental leaps between sentences.
Nearby is a transitional word of location/place. It helps to link two ideas:
Logan carried the suitcase out to the car. Regina waited patiently.
Thanks to the transition word 'nearby', we understand that she waited for him to transfer the luggage to the vehicle.
