Copy variable to array

[Johnny Rosenberg]

I have a variable that contains a path. Now I want to copy every single
directory to an array like this:
x=./abc/def/ghi/jkl/mno
# Do something here to copy x to the array y…
echo ${y[3]} # Should print ”def”.

Here's the result of my best (?) try:
$ x="./abc/def/ghi/jkl/mno"; IFS='/'; y=$x; echo ${y[0]}; echo ${#y[@]};
IFS=$'\n'
. abc def ghi jkl mno
1
$

Here's what I hoped would happen:
$ x="./abc/def/ghi/jkl/mno"; IFS='/'; y=$x; echo ${y[0]}; echo ${#y[@]};
IFS=$'\n'
.
6
$

What am I doing wrong? It seems to work if I read the path from a file with
”read -r -a”, why not from a variable?
