In the month since the Jan. 30 release, there have been tranches heard on the radio, on television, online and in print. There have been descriptions of “massive” and “enormous” tranches, “giant” and “voluminous” tranches, and — conversely — “small” tranches inside big tranches. There have been “recent” tranches and “new” tranches and “possibly last” tranches. There have been Spanish-language tranches (“tramo,” roughly) and, of course, French tranches, a natural outgrowth of its ancestry as a French verb, trancher, meaning to slice.
