〜あっての
Made possible only by 〜あっての
Meaning
"Which exists only thanks to ~", "~ is what makes it possible".
Formation
[noun A] + あっての + [noun B] （BはAあってのものだ）
Notes
Says that B collapses the moment A is removed, so it is the grammar of gratitude: お客様あっての商売. It links two nouns and cannot take a verb.
Examples
お客様（きゃくさま）あっての商売（しょうばい）です。
There is no business without customers.
