This question already has an answer here:
The golfer Tiger Woods's clubs... -or-
The golfer Tiger Woods' clubs...
The last name Woods is not biblical, etc. It is singular when it refers to the person, Tiger Woods. It is plural when it is the word, "woods".
I have, literally, seen it both ways, online and in newsprint, and ask which is correct. (I'll go out on a limb and say that the first example seems right to me, and yet it is the second example that I see more often in print and online)
Thank you very much for any education you can provide me on this matter. Sincerely, Sven
