दस (das)

numeral/adjective The number ten; used both as a counting numeral and in set phrases about round numbers and general quantities.
Sense 1 : the number 10
numeral
Frequency: high
Cultural Note: दस (das) shows up constantly in everyday money and time talk -- दस रुपये (das rupye, 'ten rupees') and दस बजे (das baje, 'at ten o'clock') are two of the most common phrases a learner will hear on the street.
Common Mistakes: 1) Learners sometimes try to inflect दस (das) like an adjective before a noun, but numerals stay invariant regardless of the noun's gender or number: दस लड़के (das ladke, 'ten boys') and दस लड़कियाँ (das ladkiyaan, 'ten girls') both use the same form.

मुझे दस रुपये दे दो। Give me ten rupees.

Sense 2 : a round/approximate number, 'several, a good few'
adjective Used loosely, not as an exact count, in phrases like दस बातें (das baaten, 'a good few things/points') or दस काम (das kaam, 'a bunch of tasks').
Synonyms: कई (kaii, several)
Frequency: medium
Cultural Note: You'll hear this in complaints like मुझे दस काम करने हैं (mujhe das kaam karne hain, 'I have a ton of things to do') -- the exaggeration is deliberately vague, much like English's 'a million things.'
Common Mistakes: 1) When दस (das) is used this way it does not mean exactly ten -- it signals 'quite a few' or 'a lot to deal with,' similar to how English speakers say 'a dozen things to do' without meaning exactly twelve.
Sample Sentences:
मुझे दस काम करने हैं। I have a ton of things to do.
(mujhe das kaam karne hain।)
Register: Casual -- Mood: Indicative -- Tense: Present -- Voice: Active
