The name given by the Dúnedain to the second month of the year. The word Nínui comes from the Sindarin language, and its Quenya equivalent is Nénimë. Both words seem to be related to the Elvish stem-word 'nen', relating to water and wetness. In one case, indeed, the word is translated as 'tears', but used as a month-name it is presumably a reference to the late winter rains and their results.
