Something that has not been affected or changed in any way, remaining in its original state.

Untouched → It is formed from the prefix "un-" (meaning not) and the root "touch" (from Old English "tūcan", meaning to make contact with). The suffix "-ed" indicates a past participle. The word "untouched" means not having been made contact with or altered in any way.
Think of 'not' ('un-') making contact ('touch') — that's why untouched means something that hasn't been touched or changed.
