Word generation with nested loops

I made this script which generates all combinations of lowercase letters and numbers and echoes them. It works, but I am wondering if there is a way to simplify the process of adding a new char instead of my current way of having to make a new function for every new character I want to add. Here's my script:

declare -r LIST=$(echo {a..z} {0..9})

function word_generation_2 {

for char1 in ${LIST}; do

for char2 in ${LIST}; do

echo ${char1}${char2}

done

}

function word_generation_3 {

for char1 in ${LIST}; do

for char2 in ${LIST}; do

for char3 in ${LIST}; do

echo ${char1}${char2}${char3}

done

}

function word_generation_4 {

for char1 in ${LIST}; do

for char2 in ${LIST}; do

for char3 in ${LIST}; do

for char4 in ${LIST}; do

echo ${char1}${char2}${char3}${char4}

done

}

function word_generation_5 {

for char1 in ${LIST}; do

for char2 in ${LIST}; do

for char3 in ${LIST}; do

for char4 in ${LIST}; do

for char5 in ${LIST}; do

echo ${char1}${char2}${char3}${char4}${char5}

done

}

for ((i = 2; i < 6; i++)); do

word_generation_${i}

done

Output is:

...

99999

I want to keep it like that. First all combinations of 2 chars, then all combinations of 3 chars, etc.
