Definition of the word fall upon

The phrase "fall upon" initially converged into the English vocabulary during the Middle English era (1100-1475). Its origin can be traced back to the Old Norse term "falna," which signified the act of falling heavily in a harmed or destructive condition. During the Viking expeditions, "falna" entered the Old English lexicon in a form close to "falan," which manifested as the Old English noun "falman" which meant a falling, tumble, or crash. Later on, during the Norman Conquest, Norman-French migrated to England, who brought their version of this phrase, "tomper sur," which translated to "fall upon." The English language, seeing the noteworthy French advances, adopted "fall upon" from the French "tomber sur" in lieu of the Old English "falman," whose semblance vanished ahead of the 16th century. The existence of this Old Norse word, however, has witnessed its influence on the development of related terminologies in several Germanic dialects, such as "fallen" in German, "falla" in Swedish, and "falle" in Danish. In conclusion, "fall upon" is a descendant of the Old Norse "falna," a term that evolved into various Germanic dialects and circulated across England after its inception during the Viking expeditions. The phrase then adapted from French during the Norman Conquest and overtook the Old English "falman" to become an integral part of English lexicon.
