In the context of inferring, the term micro-level refers to the inferring that takes place between the word and sentence level. For example, in the sentences: "Bob went to the store. He bought an ice cream." a micro-coherence inference would be linking "He" to "Bob."
This inference is forward because it it involves an inference about something that has yet to be read. It is micro because is occurs at the word level. It is cohesive because it is necessary to know that "he" refers to "Bob" in order to understand the second sentence.
