The compound word **孤僻** is formed through the combination of two semantically related characters: **孤** (gū), which originally means "orphaned" or "solitary," and **僻** (pì), which means "secluded," "remote," or "eccentric." Together, they create a binome where each character reinforces the other to describe a personality trait. **孤** emphasizes the state of being alone or isolated, while **僻** adds the dimension of being withdrawn, unsociable, or idiosyncratically distant from others. The formation is a typical example of a coordinated compound in Chinese, where two near-synonyms merge to form a single, more nuanced adjective meaning "reclusive," "antisocial," or "withdrawn in character."
