हर कोई (har koii)

pronoun A compound pronoun meaning 'everyone, everybody' -- built from हर (har, 'every') plus कोई (koii, 'someone/anyone'). One straightforward sense.
Sense 1 : everyone, everybody
pronoun Grammatically singular -- takes third-person singular verb agreement even though it refers to a group of people.
Synonyms: सभी (sabhii), सब (sab), हर एक (har ek)
Frequency: high
Cultural Note: हर कोई (har koii) is the everyday, slightly more emphatic cousin of सभी (sabhii) or सब (sab) -- where सब (sab) sounds like a collective mass ('everyone, as a group'), हर कोई (har koii) picks out each individual person one by one, closer to English 'every single person.' You will hear it constantly in casual complaints like हर कोई यही कहता है (har koii yahii kahtaa hai, 'everyone says the same thing') -- a classic Delhi auto-rickshaw or chai-stall grumble.
Common Mistakes: 1) Learners sometimes pluralize the verb after हर कोई (har koii), e.g. saying हर कोई जाते हैं (har koii jaate hain) instead of हर कोई जाता है (har koii jaataa hai) -- the phrase is treated as singular. 2) हर कोई (har koii) is not marked with ने (ne) any differently from कोई (koii) -- it follows the same oblique/agreement pattern as the base word कोई (koii), so the perfective still agrees with the object if there is one, just as with कोई (koii) alone.
