We develop the structure theory for transformations of weakly geometric rough paths of bounded 1<p$1 < p$‐variation and their controlled paths. Our approach differs from existing approaches as it does not rely on smooth approximations. We derive an explicit combinatorial expression for the rough path lift of a controlled path, and use it to obtain fundamental identities such as the associativity of the rough integral, the adjunction between pushforwards and pullbacks and a change of variables formula for rough differential equations (RDEs). As applications we define rough paths, rough integration and RDEs on manifolds, extending the results of Cass, Driver, and Litterer (Proc. Lond. Math. Soc. (3)111(2015), no. 6, 1471–1518) to the case of arbitrary p$p$.
