How to split one string into multiple strings separated by at least one space in bash shell?

by

I like the conversion to an array, to be able to access individual elements:

sentence="this is a story"
stringarray=($sentence)

now you can access individual elements directly (it starts with 0):

echo ${stringarray[0]}

or convert back to string in order to loop:

for i in "${stringarray[@]}"
do
  :
  # do whatever on $i
done

Of course looping through the string directly was answered before, but that answer had the the disadvantage to not keep track of the individual elements for later use:

for i in $sentence
do
  :
  # do whatever on $i
done
