おかげで・ おかげだthanks to

How to form it
Noun + の + おかげで / Plain form + おかげで
薬のおかげで, 練習したおかげで, よかったおかげで. A な-adjective takes な: 静かなおかげで. At the end of a sentence it is おかげだ or おかげです.
Credit for a good result
What follows is something you are glad about, very often a "was able to". The credit can go to a person, to the weather or good luck, or to your own hard work. When someone did it for you, the verb before it usually ends in てくれた.
