versiegeln vs sperren
to block / to ban
'sperren' and 'versiegeln' can both mean that no one is allowed to enter a place. 'sperren' is more general: a road, an entrance, or an area is closed, or access is forbidden. 'versiegeln' is more specific and sounds more official. It means that, for example, the police close an apartment or a crime scene in such a way that no one may enter and nothing should be changed. Learners may confuse the words because both prevent entry. 'sperren' fits many ordinary situations; 'versiegeln' fits especially in contexts involving authorities, security, or evidence.
