      abstract     = {An appealing explanation for the Planck data is provided by
                      inflationary mod els with a singular non-canonical kinetic
                      term: a Laurent expansion of the kinetic function translates
                      into a potential with a nearly shift-symmetric plateau in
                      canonical fields. The shift symmetry can be broken at large
                      field values by including higher-order poles, which need to
                      be hierarchically suppressed in order not to spoil the
                      inflationary plateau. The herefrom resulting corrections to
                      the inflationary dynamics and predictions are shown to be
                      universal at lowest order and possibly to induce power loss
                      at large angular scales. At lowest order there are no
                      corrections from a pole of just one order higher and we
                      argue that this phenomenon is related to the well-known
                      extended no-scale structure arising in string theory
                      scenarios. Finally, we outline which other corrections may
                      arise from string loop effects.},
