La palabra del día: Confinamiento

Masculine noun. Temporary condition imposed by governmental authorities (as during the outbreak of an epidemic disease) in which people are required to stay in their homes and refrain from or limit activities outside the home involving public contact (such as dining out or attending large gatherings). E.g.: Las autoridades impusieron el confinamiento en la ciudad el 23 de enero: Authorities placed the city under lockdown on Jan. 23.
The verb is confinar but it is generally used more to express the idea of ‘to impose isolation or seclusion to someone’. dc
