estriol

the word 'estriol' is a modern scientific compound formed in english. its first element, 'estr-', is extracted from 'estrogen', the class of hormones to which it belongs. the term 'estrogen' itself originates from the greek 'oistros', which referred to a gadfly, a state of frenzy, or vehement desire, metaphorically linking to the hormone's role in inducing estrus (heat) in animals. the final element '-ol' is a standard chemical suffix derived from latin 'oleum' (oil), used systematically to denote alcohols. thus, 'estriol' logically names a specific alcohol compound within the estrogen family, its construction following the precise, formulaic patterns of biochemical nomenclature.

Structure: estr (estrogen) + i + ol (chemical suffix) estr (from english 'estrogen', itself from greek 'oistros' meaning gadfly, frenzy, mad desire); i (connective vowel); ol (suffix in chemistry denoting an alcohol or phenol, from latin 'oleum' meaning oil).
