No, fenugreek leaves and curry leaves are not the same things at all. Fenugreek leaves are harvested from the plant Trigonella foenum-graecum whereas curry leaves are harvested from the Murraya koenigii plant.
Curry leaves are similar in appearance to bay leaves. They come from the same family of plants as citrus fruits. They have a peppery and citrusy flavor which is vastly different from the maple syrup tones found in fenugreek leaves.
You cannot use fenugreek and curry leaves interchangeably in recipes. The flavors are very different and will dramatically alter your finished dish.
