Old variant of 最. Phonosemantic compound. 宀 represents the meaning and 取 represents the sound. Based on the original meaning "gather". The meaning later shifted to "accumulate", "many" and "most".
㝡 and 取 don't sound similar in modern Mandarin due to historical phonetic changes. They were more similar in older Chinese.㝡 /*[ts]ˤot-s/ 取 /*tsʰˤoʔ/, /*tsʰoʔ/, /*[ts]ʰoʔ-s/
