Etymology

Origin of encumber

First recorded in 1300–50; Middle English encombren, encombre, encomber, from Anglo-French, Middle French encombrer, equivalent to en- prefix + -combrer, verbal derivative of combre “dam, weir,” from early Medieval Latin combrus, from Gaulish comberos (unrecorded) “confluence, bringing together” (compare Quimper, in Brittany, from Breton Kemper ); see en- 1, com-, bear 1

Explanation

To encumber is to weigh someone or something down with a physical or psychological burden. You may find yourself encumbered by a heavy backpack or with anxieties. Either way, it's a heavy load to bear! You can also use encumber to describe something that restricts you in some way: you're so encumbered by your homework load you can’t go to the concert Saturday night. The root, cumber, has several shades of meaning — including "to burden" and "to be overwhelmed."
