What does yestermorn mean?
Yestermorn is a chiefly literary English word meaning “the previous morning.” It may be used as a noun, as in “He arrived before breakfast on yestermorn,” or as an adverb, as in “We spoke yestermorn.” The expression belongs to an older, formal style: modern speakers normally say “yesterday morning,” which is clearer and far more common. Yestermorn carries no special emotional meaning of its own, but its compact, slightly archaic tone can lend a narrative or period atmosphere to prose. It is useful chiefly for stylistic effect, preserving the sense of an event’s time while giving it a more formal cadence. The word comes from combining the element “yester,” preserved in words such as “yesterday,” with “morning,” in a formation parallel to “yesternight” and “yestereve.” Outside literary or deliberately period writing, choosing the familiar two-word form will usually sound more natural.
