That article got long, and I promised to follow it up later. Well … it’s later. And this is the follow-up.
The Morphology Filter is good for word-level and paragraph-level work. That is, when you are reading through the text and noticing morphological trends, the Morphology Filter helps these sorts of things jump out at you.
Upon noticing what seems to be a concentration of a particular morphological criteria in a particular paragraph or section, the next question is: Does this happen elsewhere in the book, or is this unique? In other words, with the Morphology Filter, you’re looking at the trees (or perhaps a particular grove of trees). But you need to step back and look at the whole forest now. This is what Verb Rivers help you to do.
(Holding back the urge to mix metaphors and crack a joke about going “over the river and through the woods” … )
