 Informative sentences are more for the mutual benefit of both the listener "and" the speaker, and, in fact, require more of an interaction between both parties involved.They are more intentional or premeditated, less essential, more cooperative, and they aim to either provide or retrieve information, making them quintessential abstractions.But perhaps the most differentiating quality that distinguishes informative sentences from the communicative is that the former more naturally and freely make use of displacement.
