giantess
A 'giant' describes any person or thing of unusually or abnormally large size. The word is not gender-specific: you can refer to a male or female person or other creature as a 'giant'.The term giantess was used in mythology and other fiction to refer to a female giant, usually in similar context to the term 'ogre' or 'monster'. It is now considered archaic, and certainly today we wouldn't refer to a female person suffering from gigantism, a hormonal imbalance resulting in abnormal growth, as a giantess.
