I'm gunna go ahead and say there are 7 unique shouts... if you think about it, if each shout consists of three words, then they could easily categorize each spoken word as a separate shout... I hope to god I'm wrong, but I could totally see something like that happening.=\ c'Mon 20+ unique shouts!! Haha
Actually that makes pretty good sense. Thats how I interpreted the article as well--as in each individual word is capable of a minor shout effect and as you string two or three words together they become more powerful. 7*3=21
Yeah, I could see a lot of devs doing stuff like this. I'm sure there are plenty of instances of it if I were to dig for it, I just hope to god when they say 20+ shouts they mean unique effects, not 7 different effects with three levels that very slightly in usage or power. I just can't honestly think of useful shout ideas that aren't already magic effects... well, I camt think of over 20 I mean. Is there a thread out there that people are discussing possible shout effects??
There are 60 unique words to learn, and 3 words per shout. All the words are only used in one shout each, which gives you a total of 20 unique shouts. There is no interchanging words to make different combinations.
I forgot that the article said there were over 60 words in total. With 60+ words, the idea of 7 individual, unique shouts; each with 3 varying degrees of intensity can't work, because it would mean that there was only 21 words. So I will now say there are 23 unique shouts, that each need 3 words in it to be effectively used and I will also guess, from what I read, that the longer you hold the button for some shouts the more intense the effect will be, but I would also guess that for the sake of balancing the overpowered effects that these shouts will unleash, that their delivery will be kind of slow and will leave you exposed for a few seconds, and defenseless against any enemy attack--and that being struck while in the midst of summoning a shout, would cancel the shout altogether.
Lastly, and this is to Proditus, I can't see why some words couldn't possibly be used in two different shouts. Ultimately, it is the combination of words that matters, not the individual meaning of a specific word.
