🏷️ 木 wood + 票 ticket = a wooden ticket, i.e. a label or mark
Ancient markers were wooden slips stamped with a seal — wood (木) plus ticket/slip (票) gives you something you tag or label onto things.
标 — tree 木 + 票 (ticket/phonetic)
Originally written 標, this is a semantic-phonetic compound: 木 (tree) gives the meaning and 票 supplies the sound. It first referred to the tip or top of a tree, then extended to any marker, sign, or label placed at a prominent point. The simplified form 标 keeps the same structure with a reduced phonetic.
