What does clearness mean?
Clearness is the noun describing the quality of being clear: easy to understand, see, hear, or perceive without confusion or obstruction. It applies across many domains — to prose and argument that leave nothing ambiguous, to water or air free of murk, and to images or sounds rendered distinctly. The word derives from the adjective 'clear', which traces back through Old French to the Latin 'clarus' meaning bright or evident, making it a sibling of words like 'clarify' and 'clarion'. Though once common, clearness has gradually yielded to its near-synonym 'clarity' in everyday speech, so encountering it today often signals literary or deliberately formal register. It remains fully standard English, however, valued for conveying precision, intelligibility, and transparency in both physical and abstract senses.

Clearness was once the everyday word for clarity — Shakespeare's contemporaries reached for it constantly — but over the last two centuries its younger rival 'clarity' has almost completely taken its place.

Etymology of clearness
Clearness comes from the adjective 'clear', which entered Middle English from Old French 'cler', itself derived from Latin 'clarus', meaning bright, evident, or illustrious. The noun was formed by adding the suffix '-ness' to denote the abstract quality, likely in late medieval or early modern English. It shares this Latin root with cognates such as 'clarity', 'clarify', and 'clarion', all ultimately expressing brightness or distinctness. Over time it has been largely supplanted by 'clarity', borrowed later directly from Latin.

Clearness is a formal, somewhat old-fashioned word that has been largely displaced by 'clarity' in modern usage. It remains perfectly correct and is still found in careful or literary writing, but most contemporary speakers default to 'clarity'. It carries a positive connotation of precision and intelligibility.
