Undisguised → It is formed from "un-" (meaning not) and "disguise" (from Old French *desguiser*, meaning to alter the appearance of). The word "undisguised" means not altered in appearance or straightforward.
Think of 'not' ('un-') hiding or changing something's appearance ('disguise'). This helps you remember that 'undisguised' means something that is open and clear, without any alterations.
