Etymology
Destructor comes from the parts de- ('down' or 'away') and struct ('build'), like in structure. In programming, a destructor is a special function that 'takes apart' an object or frees its memory and resources when the object is no longer needed, so the name keeps the idea of 'undoing a build' or breaking something down.
