incongruity

n. the quality or state of being incongruous; lack of harmony or consistency
n. something that is incongruous
The word "incongruity" originates from Latin incongruus (in- "not" + congruus "suitable, agreeing"). The root congru- comes from congruere ("to come together, agree"), which itself combines con- ("together") and gruere (a form related to "agree"). Over time, incongruity evolved in English (early 17th century) to describe things that are out of place or logically inconsistent, preserving the original Latin negation (in-) and harmony-related root (congru-).
