चचेरा भाई (chacheraa bhaaii)

noun This is a kinship compound meaning 'paternal cousin' (specifically, father's brother's son) -- a single-sense noun phrase covered here as one unit.
Sense 1 : cousin (father's brother's son)
noun, masculine चचेरा (chacheraa) is the adjective 'paternal-uncle's' derived from चाचा (chaachaa, father's younger brother), and भाई (bhaaii) means 'brother' -- together they specify the exact family relation rather than using the loanword 'cousin.'
Synonyms: कज़िन (kazin, English loanword, informal), भाई (bhaaii, meaning scope: generic 'brother,' often used loosely for cousins in casual speech)
Frequency: high
Cultural Note: Indian families traditionally distinguish cousins by exactly which relative they descend from -- चचेरा (chacheraa) for father's brother's kids, ममेरा (mameraa) for mother's brother's kids, मौसेरा (mauseraa) for mother's sister's kids, and फुफेरा (phupheraa) for father's sister's kids. This reflects how central the joint-family structure is: a चचेरा भाई (chacheraa bhaaii) growing up in the same house as blood siblings is extremely common, so the language gives each branch its own label rather than lumping them all under one word like English 'cousin.'
Common Mistakes: 1) Learners often just say भाई (bhaaii) for 'cousin,' which Hindi speakers understand from context but which erases the specific relation; चचेरा भाई (chacheraa bhaaii) is used when precision matters, such as introducing someone. 2) The feminine counterpart is not formed by simply changing भाई (bhaaii) to बहन (bahan) casually in speech -- चचेरी बहन (chacherii bahan) is the correct paired form, and the adjective itself changes ending (चचेरा (chacheraa) to चचेरी (chacherii)) to agree with the noun's gender. 3) Do not confuse this with मामा का बेटा (maamaa kaa betaa) or मौसी का बेटा (mausii kaa betaa) -- Hindi has distinct terms depending on which uncle/aunt (paternal vs. maternal, father's side vs. mother's side) the cousin descends from; चचेरा specifically marks the father's brother's line.
