The big seal script of character Aware is
Same as clerical script.
The song typeface of simplified character is
It lost all pictography of the character.
The original meaning and still the major meaning os the character is Aware, which is not directly from the vision but some thinking involved. When it means Aware, it is pronounced Jue1.
However it has another meaning: Sleep, when it is pronounced Jiao4. Most of time, it is used with 睡(the character for Sleep as a verb) to form a combination of word: 睡觉, in which 觉 is noun.
It is a little bit odd that the character means Aware and Sleep, two opposite meanings. I have not figured out why.
