dandruff
UK[ˈdændrʌf]US[ˈdændrʌf]
n
small, white pieces of dead skin from the scalp that are shed and seen in the hair or on the shoulders.
Etymology
the word 'dandruff' emerged in english during the 16th century, with its earliest form being 'dandriff'. its origin is uncertain but it is likely a compound from a dialect of northern england or the east midlands. the first element may be related to an old english or old norse root meaning 'scale' or 'scab', while the second element is likely connected to the old norse word 'hrufa', meaning 'scab'. over time, the pronunciation and spelling simplified to 'dandruff', solidifying its specific reference to the flaky, scaly condition of the scalp.
Analysis
the word is a simplex form; it cannot be meaningfully segmented into productive morphemes in modern english.
