An example of the Logjam Metaphor for Concepts.
Consider the word “dawn,” as in Homer’s “rosy-fingered dawn” – that is, sunrise. For the longest time, that was my main association with that sound-pattern. But, having been married to a person named Dawn for so long, associations to her are irretrievably wedged into the logjam labeled “dawn.”

I read Dawn all 20 volumes of the Aubrey-Maturin seagoing novels, which are *filled* with sentences like “We sail at dawn.” When I read such sentences, almost invariably I’d get what I can only describe as a little flash of recognition that I was not just describing a time of day but also saying her name. She has the same experience with her own name.
