Usage notes

• Do not confuse with the monetary word disburse, despite the two being near homophones and having a degree of semantic similarity (in which disbursed money may be dispersed among expenses). A mnemonic to help make the difference obvious (which uses a cognate of each word) is that d?s-burs-ing is taking money out of the purse, whereas d?-spers-ing causes something to be sparsely scattered.
