Third person singular present tense of 'clear'; makes or becomes free of obstructions, confusion, or unwanted elements.
From Old French 'cler' and Latin 'clarus' meaning bright or clear, related to the verb 'clarere' (to be bright). The word evolved from describing visual brightness to metaphorical clarity of understanding or physical removal of obstacles.
The journey of 'clear' from meaning 'bright' to 'unobstructed' reflects how humans conceptualize understanding - we use light metaphors for knowledge ('enlightenment,' 'bright ideas') and darkness for confusion. When something 'clears,' it's as if mental fog lifts to reveal bright comprehension.
