It's possible you might be thinking of a different word or root. Perhaps you meant:
* "olig-": This root means "few" or "small number," and is found in words like "oligarchy" (rule by a few), "oligopoly" (market dominated by a few firms), and "oligosaccharide" (a sugar composed of a few monosaccharide units).
* "ology": This suffix means "study of" or "science of," and is found in words like "biology" (study of life), "geology" (study of the Earth), and "psychology" (study of the mind).
