कसना (kasnaa)

verb A verb built around the idea of tightening -- literally cinching a belt or rope, and figuratively tightening one's grip, a taunt, or a schedule. Has both intransitive (to become tight) and transitive (to tighten something) uses.
Sense 1 : to tighten, cinch (something)
verb, transitive
Synonyms: जकड़ना (jakadnaa)
Frequency: medium
Cultural Note: Picture someone tightening the strap on a bed frame or a cot (chaarpaaii) with rope -- कसना (kasnaa) is exactly that everyday tightening motion. You will also hear it about tightening a belt (पेटी कसना (petii kasnaa, to tighten one's belt)) when someone is cutting costs, much like the English idiom.
Common Mistakes: 1) Learners often reach for कसना (kasnaa) when they mean 'to tie' -- but it specifically means to pull something tight or snug, not to tie it in the first place; use बाँधना (baandhnaa) for the act of tying. 2) कसना (kasnaa) is used with objects like पेटी (petii, belt) or पेंच (pench, screw) -- the sense is mechanical/physical tightening, not emotional tension, which uses other words.

Sense 2 : to taunt, jibe at, needle (someone)
verb, transitive Almost always appears in the fixed collocation ताना कसना (taanaa kasnaa, 'to throw a taunt') -- कसना (kasnaa) rarely carries this meaning alone without ताना (taanaa).
Synonyms: ताना कसना (taanaa kasnaa, set phrase), चुटकी लेना (chutkii lenaa)
Frequency: medium
Cultural Note: Family gatherings in India run on this phrase -- a rishtedaar (rishtedaar, relative) who just cannot resist a dig about your job or your weight is कसना (kasnaa)-ing a ताना (taanaa) at you, often with a smile that makes it worse.
Common Mistakes: 1) This sense essentially never occurs without its partner noun ताना (taanaa) -- saying just उसने मुझे कसा (usne mujhe kasaa) will not land as 'he taunted me'; you need उसने मुझ पर ताना कसा (usne mujh par taanaa kasaa, 'he taunted me').
