in every part of a place or thing
Colorful lanterns were hung throughout the courtyard for the festival.
The smell of fresh paint lingered throughout the house.
during the whole of a period of time
She worked remotely throughout the summer.
It rained throughout the night.
everywhere; in every part
Laughter could be heard throughout.
Dust lay thick throughout.
for the entire duration; all the time
She remained optimistic throughout.
The baby slept soundly throughout.
