unaffected
UK: ˌʌnəˈfɛktɪd | US: ˌʌnəˈfɛktɪd
adj. not influenced or changed by external factors; genuine
adj. free from artificiality or pretension
The word "unaffected" combines the prefix "un-" (Old English "un-," meaning "not") with the root "affect" (from Latin "afficere," meaning "to influence") and the suffix "-ed" (forming adjectives). Originally, "affect" implied an external force acting upon something. Adding "un-" negates this, creating a term for something untouched by influence or artificiality. Over time, it evolved to describe naturalness in behavior or state.
