A common Filipino
term used to describe a hand-gesture of approval. Hand-gesture is described to be in a form of a right-handed thumbs-up
wherein thumbs are flinted against each other by two persons when a task is completed as a sign of approval. Origin of the word is said to come from a Spanish-based creole
called "Chavacano" which is a mixture of Visayan
dialect and Spanish
language. The word is a combination of two words which are 1.) from the Visayan word of "santik" which means "flint" in English and 2.) from the Spanish word "aqui" which have in time mutated to "aki" or "ki" on the Spanish-based creole which means "here" in English hence "santik" + "ki" = "santiki".
