2. 2
   verb

   Simple past and past participle of register.

   The thermometer registered a record high yesterday afternoon.

   He had registered his complaint before leaving the building.

   Note

   A regular form: one spelling serves the simple past (she registered last week) and the participle after have or be (has registered, was registered). The reading to watch is after be. With an agent or a single event, it is passive (the letter was registered by the clerk). When it describes a lasting condition, it shades into the "on the list" adjective or the postal sense: registered to vote, a registered letter.

3. 3
   adjective

   Recorded in a postal register so the item's location can be tracked, sometimes carrying added insurance to cover loss.

   The court required that the summons be sent by registered mail.

   Each registered parcel can be traced through every stage of delivery.

   Note

   A postal term in which the item itself goes on the list: the letter or parcel is recorded, not a person as in the sense of being officially enrolled. That record follows the item through each handling stage, so its whereabouts can be traced. Insurance against loss is sometimes added for a further fee, but it is an extra and not what registration means. The usual collocation is registered mail.
