Verisimilitude

Verisimilitude \ver-uh-suh-MIL-uh-tood\ or \ver-uh-suh-MIL-uh-tyood\ , noun;
1. The appearance of truth; the quality of seeming to be true
2. Something that has the appearance of being true or real

This word dates to the 1600's from French verisimilitude, which is derived from Latin verisimilitudo ("likeness to truth"). The Latin word is from veri + similis (neuter of verus "true" + "like, similar"). Verus is the forebear of very and similis is the forebear of similar.
