What does decapitalize mean?
To decapitalize is, most commonly, to strip away a capital letter—to turn 'London' into 'london,' or to render an entire passage in lowercase. The verb belongs chiefly to typography, editing, and computing, where programmers routinely write functions that decapitalize strings for comparison or formatting purposes. A second, less frequent sense arises in finance, where an institution or economy may be said to be decapitalized when its capital resources have been severely depleted, as by losses or crisis. The word is transparently built on 'capitalize,' prefixed with 'de-' to reverse it, so its meaning is instantly recoverable even by readers meeting it for the first time. Though it shares its dramatic prefix with 'decapitate,' nothing gruesome is implied—the only head involved is the one atop a letter. Writers use it whenever precision about letter case matters: in style guides, code comments, and editorial instructions alike.
To change a word from an initial capital letter to a lowercase letter, or to write text entirely in lowercase.
"The script decapitalizes each filename before sorting them alphabetically."
To deplete or remove the capital resources of a company, institution, or economy.
"Years of mismanagement had decapitalized the railway, leaving no funds for maintenance."
Despite sounding like something out of a horror film alongside its cousin 'decapitate,' decapitalize has never harmed anything but a capital letter—or an over-leveraged company.

Etymology of decapitalize
Decapitalize is formed straightforwardly from the verb 'capitalize,' itself derived from 'capital,' which traces back through Old French and Latin 'capitalis' ('of the head'), from Latin 'caput' ('head'). The prefix 'de-' reverses the action, yielding a word whose earliest uses appear in modern English, particularly from the nineteenth century onward as printing conventions and later computing made letter case a matter of active manipulation. Its relatives—including 'capital,' 'captain,' 'chapter,' and 'decapitate'—all descend from that same Latin root meaning 'head.'
How decapitalize is actually used
In typography and computing contexts, 'decapitalize' is often replaced by 'lowercase' used as a verb, which is more common in technical writing; 'decapitalize' remains fully acceptable and unambiguous. The financial sense is comparatively rare and appears mostly in economic and journalistic prose describing firms or economies drained of capital.
Easily confused with decapitalize
To capitalize means to make a letter uppercase or to supply capital to a business, whereas to decapitalize does the opposite of both actions—removing uppercase letters or draining capital.
