Definition
Something 'unobtrusive' doesn't attract attention and blends in well with its surroundings. Think of a quiet observer at a party, or a security camera carefully hidden from view. It implies a lack of obtrusiveness; the quality of not being blatant, showy, or intrusive. It is the opposite of something that is obvious or conspicuous. An 'unobtrusive' presence goes unnoticed and doesn't disrupt the environment. Like a chameleon, it seamlessly integrates into its context.
