What does undermost mean?
Undermost means lowest in position, rank, or importance. It can describe the bottom of a physical arrangement, as in a layer of soil or the lowest branches of a tree, or be used figuratively for the least important member of a group. The word is less common than lowest and bottommost and often sounds formal, literary, or slightly unusual in ordinary conversation. Its force comes from expressing an unequivocal positional extreme: the undermost person in a photograph or the undermost level of a hierarchy. Although it is occasionally used in everyday speech, it is especially effective in descriptions that emphasize spatial arrangement, hierarchy, rank, or marginal status.
