Etymology: The verb in question derives from the root "accustom," which itself comes from the Old French "acostumer," meaning "to make familiar with." This Old French term traces back to the Latin "consuetudinem," meaning "custom" or "habit." To "accustom" someone originally involved a process of habituating them to something, making a practice or behavior familiar and regular. Adding the prefix "dis-" reverses this action, signaling a removal or undoing of the accustomed state. The prefix comes from Latin "dis-" which often denotes negation or separation. Thus, this verb formed by prefixing "dis-" to "accustom" literally means to break or remove a habit, to cause someone to cease being familiar or habituated to something. The construction follows a common pattern in English where "dis-" is combined with verbs to indicate the reversal of an action, such as "disarm" (to remove arms) or "disengage" (to detach). The verb itself likely came into use in English around the 16th or 17th century, when many such compound forms were being coined or standardized. Over time, the verb has maintained this straightforward meaning: to remove a habit, to make unfamiliar what was once familiar. It reflects the way English can build nuanced meanings through simple prefixes added to well-established verbs.
