Putrid is not a thing, it is a condition. It means rotting.
The smell of the sock is rather putrid.
The putrid compost smelt horrible.
I was extremely thirsty, but there was only a bottle of putrid water in the cell.
The basement was dark and cold, and there was a putrid smell, as if something had gone rotten in there.
putrid is to rotten/fermented as salty is to taste.
