Numbskull

NINNY

Think of a silly, overly sentimental person who might be called this in old-fashioned stories—it starts with "nin.

Numbskull" is a playful insult for someone foolish or slow-witted, and "ninny" fits perfectly as another old-fashioned term for the same idea. The clue relies on synonymy—both words mockingly describe a person lacking common sense, with "ninny" carrying a slightly softer, almost silly tone. Think of it like calling someone a "dope" or "dolt," where the answer swaps in a less common but equally fitting word. No tricks here, just straightforward word matching.
