What is an alternative to 'pre-' vs. 'post-' or 'before' vs 'after' that sorts in the order of events?

If ordered alphabetically , pre goes after post, because the 2nd character r of pre goes after the 2nd character o of post. Same issue with before and after because of their 1st characters. Is there an alternative to these pairings that, if ordered alphabetically, would place the equivalent of pre or before before its counterpart post or after? Like in Spanish, ‘antes’ vs. ‘despues’, but in English (antes means before and despues means after).
