Inverted breve or arch is a diacritical mark, shaped like the top half of a circle (   ̑ ), that is, like an upside-down breve ( ˘ ). It looks similar to the circumflex ( ˆ ), but the circumflex has a sharp tip; the inverted breve is rounded: compare  â Ê ê Î î Ô ô Û û (circumflex) with Ȃ ȃ Ȇ ȇ Ȋ ȋ Ȏ ȏ Ȗ ȗ (inverted breve).
