What does apert mean?
Apert is an archaic English adjective meaning open, unconcealed, or plainly evident, and — applied to people — frank and candid in manner. A statement could be described as apert if it left nothing hidden or ambiguous, and a person could be apert if they spoke their mind freely and without guile. The word derives from Latin apertus, the past participle of aperire ('to open'), reaching English through Old French, which makes it a close relative of modern words such as aperture, apparent, and overt. Although once a serviceable term in ordinary English, apert has been almost entirely displaced by those younger rivals and now survives chiefly in historical texts and antiquarian interest. It remains useful to readers of early modern literature, where encountering it unexplained can be puzzling, and to anyone who enjoys tracing how words rise, flourish, and quietly retire from use.

Apert and 'overt' are essentially siblings — both descend from Latin aperire, 'to open' — but overt thrived while apert faded into literary history.

Etymology of apert
Apert comes from Latin apertus, the past participle of aperire, meaning 'to open' or 'to uncover'. The word passed into Old French as apert, retaining the sense of something open or manifest, and from there entered medieval and early modern English. It shares this Latin root with aperture (an opening), apparent (visible, evident), and overt, which came through a different Romance route but preserves the same underlying idea of openness. Over time apert fell out of general use, supplanted by plainer and more familiar alternatives.
How apert is actually used
Apert is archaic and rarely encountered outside historical literature, older dictionaries, and scholarly writing on early modern English. Writers today would almost always choose 'open', 'evident', or 'overt' instead. Its survival gives it antiquarian charm rather than everyday utility.
