This naturally leads us to soften some of its features, and thus palliate approaches extenuate till they have become nearly or quite identical. "To palliate is not now used, though it once was, in the sense of wholly cloaking or covering over, as it might be, our sins, but in that of extenuating; to palliate our faults is not to hide them altogether, but to seek to diminish their guilt in part."

| palynology |
The identification of plants through the remains of their pollen grains. Pollen is morphologically species-specific; the pollen grains of each species are recognizably different from the pollen of all other plant species. Recovery at an archaeological site of the preserved pollen of particular species allows for the reconstruction of the plant community present when the site was occupied which can, in turn, inform us of the climate at the time.
