信（xin）
Name meaning
信 (xin) means trust, good faith, reliability and keeping one's word.
Practical naming use
信 (xin) is one of the clearest Chinese virtue characters because it joins speech and human reliability. In classical thought it is not only private honesty but the basis of friendship, reputation and public order. As a name character, it feels steady, credible and quietly strong rather than ornamental.
Pair 信 (xin) with characters such as 安 (An) for grounded trust, 文 (Wen) for cultured honesty, 远 (Yuan) for breadth or 雅 (Ya) for softer refinement. The second character should keep the name human rather than doctrinal.
信然 (Xinran): Xin means trust and Ran means naturalness. The name feels genuine and unforced, like a person whose reliability comes across in ordinary behavior rather than formal promises.
