ceci means 'this' in French. 'pari' (masculine noun, plural 'paris') means a bet or gamble.
Ça, ce, ceci and cette are French equivalents of the English word "this." Context makes clear whether a feminine or masculine singular adjective (cases 2, 4), stand-alone object and subject pronouns (examples 1, 3) or a subject pronoun (instance 2) suit. The respective pronunciations will be "sa," "suh," "suh-see" and "set" in French.
