'Friends' home' is a compound noun formed by combining 朋友 (péngyou, 'friend') and 家 (jiā, 'home' or 'house'). Unlike English, Chinese does not use an apostrophe or possessive 's'; instead, the possessor (friend) directly modifies the possessed noun (home), following the standard [modifier + head] structure. This phrase is neutral in register and commonly used in everyday speech when referring to where a friend lives—especially when discussing visiting, staying, or meeting there.

The word emphasizes location rather than ownership: it refers to the physical place where a friend resides, not necessarily their family home or property. It’s frequently used in invitations ('Let’s go to your friend’s home'), plans ('I’m staying at my friend’s home this weekend'), or casual explanations ('I’ll be late—I’m picking something up at my friend’s home'). It can refer to any residence—apartment, house, dorm room—as long as it’s where the friend lives.
