My first is in seven but not in eight
My second is in dote but not in date
My third is in three and also in ten
And also in twelve and brings this word to an end
My next is a letter on its own
It makes a word while standing alone
My fifth is in the mountains, no word of a lie
My sixth is the letter that sounds just like why
My seventh is in dash but not in cache
My eighth isn’t garbage but is found in the trash
My ninth is in one and also in nine
My tenth is in four but not in five
My eleventh is a letter you’ve had before
And solving this should send you right out of the door
And this brings my puzzle to an end
I hope it hasn’t driven you round the bend!
Find a place that’s safe to park...
And be careful if you head out there in the dark!
