About
The character "囫" is formed with the enclosure radical 囗 and the component 勿, and it only functions within the compound "囫囵". This term, denoting something entire or undivided, entered the lexicon by the medieval period, specifically documented in Yuan dynasty texts. Its meaning has consistently referred to a state of completeness, as seen in the enduring idiom "囫囵吞枣". The character's structure and its role in this binome have remained unchanged since its establishment.
