數

Components:

攴 (칠 복) – “to strike, to tap,” often used to indicate actions related to handling or tallying;

婁 (끌 루) – phonetic element, lending the sound.

Originally meant “to strike marks for tallying”, which evolved into “to count” and “number”.

數 is a multi-reading character:

수 - is the most common reading (both as noun “number” and verb “to count”);

삭 - appears in set expressions like 數大葉 (삭대엽 – a traditional Korean gasa song form);

촉 - for “dense” is nearly obsolete in modern use.
