Definition of Trustworthy
Trustworthy is an adjective used to describe someone or something that is reliable, honest, and deserving of trust. A trustworthy person is someone you can depend on to be truthful, keep their promises, and act with integrity. A trustworthy object or system is one that functions as expected and can be relied upon to perform its intended purpose without failure or deception.
The word “trustworthy” implies a sense of security and confidence. It suggests that the subject is not likely to betray your trust or act in a way that would be detrimental to your interests.
This characteristic is highly valued in personal relationships, professional settings, and society as a whole. A trustworthy individual is often seen as a leader and someone who inspires confidence in others.
In a broader sense, “trustworthy” can also apply to information, sources, or institutions. A trustworthy news source, for example, is one that adheres to journalistic ethics and provides accurate and unbiased reporting.
A trustworthy website is one that protects user data and does not engage in malicious activities. The essence of “trustworthy” is consistency, reliability, and a commitment to honesty.
Structural Breakdown of Trustworthy
The word “trustworthy” is formed by combining two elements: the noun “trust” and the adjective suffix “-worthy.” Understanding the etymology of the word can shed light on its meaning and usage.
- Trust: This refers to a firm belief in the reliability, truth, ability, or strength of someone or something. It involves a sense of confidence and reliance.
- -worthy: This suffix indicates that something possesses the qualities or characteristics that merit the specified noun. In this case, it means “deserving of trust.”
Therefore, “trustworthy” literally means “deserving of trust.” The suffix “-worthy” is commonly used to form adjectives that describe something as having value or merit, such as “newsworthy” (deserving of being reported as news) or “roadworthy” (fit to be driven on the road). The combination of “trust” and “-worthy” creates a word that encapsulates the idea of reliability and integrity.
Analyzing the structural components helps us appreciate the nuanced meaning of “trustworthy.” It’s not simply about being honest; it’s about consistently demonstrating qualities that inspire confidence and reliance. The word suggests a proactive effort to earn and maintain the trust of others.
