> English word · Noun · IPA /ˈɹɪkɪts/ · frequency rank #58,980

## Definitions
1. A disorder of infancy and early childhood due to a deficiency of vitamin D, causing soft or weak bones.

## Etymology
Unknown. Originally a local name for the disease in Dorset and Somerset, England. Occasionally postulated to be derived from a Dorsetian dialectal term *rucket (“to breathe with difficulty, wheeze”), but the semantic connection is tenuous. See rachitis, but the medical name was chosen purposefully by English physician Daniel Whistler from phonetic similarity to rickets.
