तादाद (taadaad)

noun A single-sense noun meaning 'number' or 'quantity' -- used when talking about how many of something there are, especially people.
Sense 1 : number, quantity (of people or things)
noun, feminine
Synonyms: संख्या (sankhyaa), गिनती (gintii)
Frequency: medium
Cultural Note: You will hear तादाद (taadaad) a lot on the news when reporters talk about crowd sizes or casualty counts -- भीड़ की तादाद (bhiid kii taadaad, 'the size of the crowd') is a very standard phrase. It is an Urdu-origin word that has been fully absorbed into everyday Hindi, so it does not feel especially formal or literary the way some other Urdu borrowings do.
Common Mistakes: 1) Learners often reach for संख्या (sankhyaa) by default, but तादाद (taadaad) is just as common in spoken Hindi, especially when talking about crowds of people -- लोगों की तादाद (logon kii taadaad, 'the number of people'). 2) It takes की (kii) before the thing being counted, matching its feminine gender, not का (kaa) or के (ke).
