Scrabble?! CHIRALITY

Definitions of CHIRALITY in various dictionaries:

Chirality is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek (kheir), "hand," a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object. A chiral object and its mirror image are called enantiomorphs (Greek, "opposite forms") or, when referring to molecules, enantiomers. A non-chiral object is called achiral (sometimes also amphichiral) and can be superposed on its mirror image. If the object is non-chiral and is imagined as being colored blue and its mirror image is imagined as colored yellow, then by a series of rotations and translations the two can be superposed, producing green, with none of the original colors remaining. The term was first used by Lord Kelvin in 1893 in the second Robert Boyle Lecture at the Oxford Univers
