IPA: /əˈpɜːrtənəns/
KK: /əˈpɜːrtənəns/
An item or right that is added to something more important, often related to property or equipment used for a specific purpose.
The appurtenance of the house included a garage and a small garden.
Appurtenance is formed from "ad-" (meaning to or towards) and "portare" (meaning to carry), combined with the suffix "-ance" (indicating a state or quality). The term originally referred to something that is carried along with or belongs to something else, indicating a supplementary or accessory nature.
Think of something that is 'carried along' ('portare') with another item, which helps you remember that an appurtenance is something that belongs to or is associated with something else.
