Just for fun...
My 1st is in candle, but not in wax,
My 2nd is in cash, but not in tax.
My 3rd is in plunder, but not in waste,
My 4th is in basket, but not in case.
My 5th is in oblong, but not in square,
My 6th is in father, but not in sir.
My 7th is orange, but not in plum,
My 8th is in clever, but not in dumb!
Who am I?
:)
