deplannen

Deplannen is a Dutch verb formed by prefixing de- to plannen (to plan). The attested sense is to reverse, undo, or cancel plans that have been made, such as withdrawing a proposed schedule or removing elements from a previously agreed plan. Because Dutch has established terms for these notions—annuleren, afblazen, uitstellen, or herplannen—the use of deplannen is relatively rare and often regarded as a neologism or informal, depending on the context. In some cases it may appear in planning notes, internal communications, or informal discourse to indicate that a planned course of action is being reversed.

Linguistically, deplannen demonstrates how the de- prefix can signal reversal or negation when attached to a verb, here plannen. Its precise meaning can vary with context, and many speakers will opt for more standard expressions. The term is more commonly encountered in informal writing or in places where teams try to coin concise shorthand for rapid planning changes. In formal writing, or in official policy documents, alternatives such as annuleren, afblazen, or herplannen are typically preferred.

In aviation contexts, the related concept of disembarking from a plane is not normally expressed as deplannen in Dutch; uitzappen of van boord gaan are the usual terms, while the English loanword deplane may be encountered in some technical or international texts.
