Originally a pictograph of engraved jade, now written as 琱. 口 (mouth) indicates that the character is only "mouthed", i.e. only used for its phonetic value. In simplified Chinese 周 is also used to mean "week", while in traditional Chinese this meaning is written with a separate character 週. Phonosemantic compound. 至 represents the meaning and 刂 represents the sound. These notes explain the characters’ formation. Learn 周到 as a complete modern word rather than mechanically adding isolated character meanings.
