güvenlidir

Güvenlidir is a Turkish predicative form meaning "it is safe" or "it is secure," and, depending on context, "it is reliable." It functions as the third-person singular present tense form of güvenli when used as a predicate, often in formal or written Turkish. The root güvenli comes from güven ("trust, safety") plus the suffix -li ("having the quality of"), yielding "having safety." Turkish sometimes uses the emphatic copula -dir in such constructions, producing güvenlidir to stress the assertion that something is safe or trustworthy; in everyday speech, speakers may simply say güvenli.

Güvenli and güvenilir are related but not interchangeable. Güvenli focuses on physical safety or security (a secure door, a safe environment, secure data), whereas güvenilir refers to reliability or trustworthiness (a dependable person or source). Güvenlidir can thus be used to describe either safety or reliability, depending on the context, but in many situations güvenli or güvenilir might be preferred for clarity.

Common usage examples include: "Bu site güvenlidir" (This site is safe/secure), "Bu bilgi güvenlidir" (This information is trustworthy), and "Bu cihaz güvenlidir" (This device is secure). The word can appear in product descriptions, safety notices, and security assessments. Related terms include güvenlik (security), güvenilirlik (reliability), and güvenmek (to trust).
