A singular transition is a transition in which only one foot ever touches the ground before initiating the next trick. Arguably, it is the rampant and proficient use of singular transitions, such as the swingthrough, that separates tricking from other acrobatic arts. Singular transitions are inherently eye catching because the first trick is landed on one leg, where momentum is directed into the second trick which is performed from the same leg.

Definition: A transition where in-air leg continues on a linear path past the base leg, creating or maintaining momentum to initiate the next trick.
The Swingthrough transition comes in two flavors - backswing and frontswing.
Backswings are the more common of the two, and can be seen in the above video example: the Raiz s/t Gainer Semi or the Double Cork s/t Double Cork
Frontswings (often mislabeled as Carrythroughs) can be seen in the above video example: the Aerial Semi s/t Raiz or the Gainer Semi s/t Raiz
A swingthrough with a stance change or added pivot in the middle. Often confused with frontswing.
A swingthrough into an inside flip. For inverts and verts.
Singular landing where in-air leg travels towards the ground as if it were going to land, but it's path rebounds into the next takeoff before touching the ground. ("missing the ground"). If the foot were to touch, it would often be considered a reversal.
A one legged punch, or a faster version of the missleg.
