📝 登 = ascend/record + 记 = note/mark → record your name in the book
登 means to ascend or to enter into a record; 记 means to note or remember. Together 登记 is the act of entering your name into an official record — registering, checking in, signing the ledger.
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.'
记 — speech radical 讠 (言) + self 己
记 is a semantic-phonetic compound. The left side 讠 (the 'speech' radical, simplified from 言) signals meaning related to words or recording, while 己 ('self') supplies the sound. Together it conveys writing down or remembering — noting things in words.
