@kennethamy,
Talk may refer to:
* Conversation, interactive communication between two or more people.
* Speech, the production of spoken language.
I believe lions can converse (though in an incredibly oversimplified version of what we generally consider conversation), but do not have a language.
Fixed language as in; "I am going to break your leg if you do that!" While casual conversation allows exceptions, this means that you have the intent to break the leg of the individual to whom you speak. However for lions, it's much different. A pride master might spot a cub trying to do something he disliked, and growl threateningly. This does not necessarily mean that he would break the leg of the cub, it could mean that he would give him a slap, or tear his jugular out and watch him bleed to death, even if that's unlikely. The cub doesn't know exactly what the lion will do, but he knows that if he does whatever it is displeases the pride master, he will be hurt. So whether or not the language is fixed, we can clearly see the same general intent in both situations.
