Opletten

Opletten is a Dutch verb meaning to pay attention or to be careful, to watch out. It is used when someone should focus on what they are doing to avoid mistakes or danger. The action can be directed at something specific, as in “Let op de verkeersborden” or “Let op wat je zegt.” The common imperative form is “Let op!” which functions as a warning or attention cue.

The word is widely used in everyday speech, education, work, and safety contexts. Examples include safety instructions, driving, and classroom communication: “Tijdens het oversteken moet je opletten,” “Let op wat er gebeurt,” or “We moeten opletten bij het bedienen van de machine.” In many cases the verb appears with a direct object or prepositional phrase indicating what to notice. The noun form is less common; more typical are the related terms “oplettendheid” (attentiveness, vigilance) and the adjective “oplettend” (attentive), as in “een oplettend kind” or “je moet oplettend zijn bij het laden van de machines.”

Relation to other concepts: opletten describes moment-voor-moment aandacht in alledaagse situaties, in contrast with broader concepts such as concentration or waakzaamheid. It often conveys practical, actionable attention in daily activities rather than formal vigilance or long-term focus. The term remains a staple in safety guidelines, education, and routine communication, reflecting its role in signaling carefulness and awareness in everyday life.
