Answer :

alliteration rain poem :
Rain
Rain races onto the porch
Hitting hard like
Rockets rushing in a race to the glass.
Rattling rain, rattling the window panes.
The droplets dance daintily
Until they cleverly connect in
A pool of promise for a rainbow.
the word rain alliterates with:
ran, rest, roy, road, reprise, reptiles, rabbit, rat, race, racial, racket, radio, radiation and much more ....
Hope this helps you! =')
