The Penguin Dictionary of Architecture (third edition) was published in 1980. It was created for Penguin Reference and compiled by John Fleming, Hugh Honour and Nikolaus Pevsner.

It defines joggle or joggling as: ‘Masons’ terms for joining two stones in such a way as to prevent them from slipping or sliding by means of a notch in one and a corresponding projection in the other. It is often seen exposed on the face of a flat arch. If the joggle is concealed, it is called a ‘secret joggle’.

The function of a joggle as applied in masonry terms has been adopted in other aspects of construction and related terminology. There are table or bed joggles, tongued and grooved joggles and slate or metal joggled joints.

== Joggle bending ==

Joggle bending is an expression used to describe an offset bend where two opposite bends with equal angles are formed in a single action. This configuration creates a bend profile and an offset between the unbent face and the resulting flange. The joint that is formed should be thin and smooth.

== Sheet metal joggles ==

The premise of joggle joints is used in sheet metal, where the joggle joint is an offset or notch that is created at the place where stringers and formers meet. It is used to create space for a sheet or another mating part. The joint provides a clean connection in the splice.

Joggle joint coping is sometimes used in types of roofing.
