आदत (aadat)

noun A single-sense noun: 'habit.' Comes from Arabic/Urdu via Persian into Hindi, and is extremely common in everyday speech about routines, tendencies, and personal quirks.
Sense 1 : habit, habitual tendency
noun, feminine Very often used with पड़ना (padnaa) as आदत पड़ना (aadat padnaa, 'to develop a habit') in a dative-subject frame -- मुझे आदत पड़ गई है (mujhe aadat pad gaii hai, 'I have developed the habit') -- and with डालना (daalnaa) as आदत डालना (aadat daalnaa, 'to cultivate/instill a habit') for the agentive version.
Synonyms: स्वभाव (svabhaav, more like 'nature/temperament'), आदत-सा (aadat-saa, colloquial intensifier form)
Frequency: high
Cultural Note: Hindi frames habits the same involuntary way it frames feelings and needs: आदत पड़ना (aadat padnaa) means the habit 'falls upon' you, much like नींद आना (niind aanaa, sleep 'comes' to you) -- habits are things that happen to you, not things you simply do. A Delhi parent scolding a kid about a bad habit will often say यह अच्छी आदत नहीं है (yah achchhii aadat nahiin hai, 'this isn't a good habit') rather than criticizing the child directly, which softens the blame onto the habit itself.
Common Mistakes: 1) Learners often say मुझे आदत है (mujhe aadat hai) when they mean 'I am used to it' -- this is correct, but the postposition after the habit itself is की (kii), not से (se) or को (ko): मुझे चाय पीने की आदत है (mujhe chaay piine kii aadat hai, 'I am used to/have a habit of drinking tea'). 2) Confusing आदत पड़ना (aadat padnaa, habit forms on its own, involuntary) with आदत डालना (aadat daalnaa, to deliberately instill a habit, agentive) -- these are not interchangeable.
