To "rustle" means to make a series of quick, light
sounds (such as when papers rub against each other).
This word helps you imagine that
When I had laid it on the floor
I went to blow the fire a-flame,
But something rustled on the floor,
And someone called me by my name:
It had become a glimmering girl
With apple blossom in her hair
Who called me by my name and ran
And faded through the brightening air.
-"The Song of Wandering Aengus,"
William Butler Yeats
a loud noise is heard from a distance.
a girl is speaking to the poem's writer.
something has just fallen to the ground.
something small is moving in the room.
