| ## About interfaces | |
| [Interfaces](https://spec.graphql.org/June2018/#sec-Interfaces) serve as parent objects from which other objects can inherit. | |
| For example, [`Lockable`](/graphql/reference/interfaces#lockable) is an interface because both [`Issue`](/graphql/reference/objects#issue) and [`PullRequest`](/graphql/reference/objects#pullrequest) objects can be locked. An interface has its own list of named fields that are shared by implementing objects. | |
