📰 刊 publish + 登 enter = enter something into print, i.e. run it in a periodical

登 — 癶 (two feet ascending) + 豆 (ritual vessel)
Originally a pictograph showing two feet (癶) climbing up to present a ritual vessel (豆) on a raised platform. The core meaning was 'to ascend' or 'mount,' as when stepping up to make an offering. From this it broadened to 'rise, climb, record, publish.'
