पहिया (pahiyaa)

noun Basically means 'wheel' -- a solid, everyday noun with one core sense; it also shows up figuratively for cyclical processes like the wheel of a machine or system.
Sense 1 : wheel (of a vehicle, cart, machine)
noun, masculine
Synonyms: चक्का (chakkaa), चक्र (chakr, literary/technical)
Frequency: high
Cultural Note: You will hear this constantly around cycle-repair stalls and auto workshops: पहिया पंचर हो गया (pahiyaa panchar ho gayaa, 'the wheel/tire got punctured') is a classic line every scooter or cycle rider in Delhi has said at some point. Note the related word चक्का (chakkaa), which overlaps closely and is common in idioms like चक्का जाम (chakkaa jaam, 'traffic jam/wheels stuck'), whereas पहिया (pahiyaa) stays more literal and physical.
Common Mistakes: 1) Learners sometimes reach for चक्र (chakr) in casual speech about a bicycle or car tire, but that word sounds bookish or technical (as in 'chakra' contexts) -- पहिया (pahiyaa) is what you'd actually say pointing at a flat tire or a cart wheel.
Sample Sentences:
मेरी साइकिल का पहिया पंचर हो गया। My bicycle's wheel got punctured.

Sense 2 : wheel as a cyclical process or driving mechanism (figurative)
noun, masculine Used in set phrases like विकास का पहिया (vikaas kaa pahiyaa, 'the wheel of development') or ज़िंदगी का पहिया (zindgii kaa pahiyaa, 'the wheel of life'), always with an oblique possessor before it.
Synonyms: चक्र (chakr)
Frequency: medium
Cultural Note: This figurative use turns up a lot in speeches, news headlines, and motivational talk -- politicians love saying things like विकास का पहिया घूमने लगा है (vikaas kaa pahiyaa ghoomne lagaa hai, 'the wheel of development has started turning'). It is a natural, common extension of the physical wheel image, not a separate borrowed idiom.
