for loop not working for multiple lines

I have a array like this "Apple Banana Clementine Date"

I have to print like this:

1. Apple
2. Banana
3. Clementine
4. Date

Script file:

for i in "${fruits[@]}"; do
    echo "$lineno. $i "
    lineno+=1
done

output of myscript:

1.             Apple
               Banana
               Clem....

I don't understand why it is not printing lineno and also why it is printing long gap b/w 1. and Apple. Thanks.
