Actually, I only want a pre superscipt, so the following works for me \def\presuper#1#2% {\mathop{}% To prevent preceeding mathord atoms to approach \mathopen{\vphantom{#2}}^{#1}% To prevent space between prescript % and next atom. \kern-\scriptspace% remove the space introduced by superscript #2} This is not perfect, especially with characters with large left "slope" like A. Any suggestions for improving the macro? Aditya
