Cognitive linguistics views meaning as a central part of language and takes a maximalist, non-reductionist, and bottom-up approach to language. Not by cutting off or contracting the excessive flow of information, but by embracing it, cognitive linguists propose a linguistic theory grounded in the general cognitive capacities of humans. The important point is that this theory can capture the nature of language that keeps changing itself to some extent. We can view this as a mechanism of active generation in language. Based on our studies of neologism in natural and artificial languages, I will introduce aspects of language that can be related to active generation in language. I argue that, through interaction with humans, language can stay fresh and generative.
