Etymology
The origin of 'dander' is obscure, with its first recorded use in the early 19th century. The primary meaning relating to skin flakes may be an alteration of 'dandruff', which itself has a Scandinavian origin. The informal sense of "anger" likely developed from the earlier phrase "to get one's dander up," possibly influenced by the Dutch or West Flemish word 'donder', meaning "thunder," metaphorically suggesting a storm of temper. This etymological journey illustrates how a word for a physical substance can acquire a vivid figurative meaning for an emotional state.
Analysis
The word 'dander' is a simplex word of uncertain origin. It is not productively formed from identifiable, separable morphemes in modern English.
