Charms Class – Year 7, Lesson 22: Horn Tongue Hex – A Trickster’s Spell for Confusing Conversations

Professor Introduction

Welcome, students. I am Professor Cedric Hallowbrook, and today’s lesson concerns a charm often labeled as a hex, though its applications range from deterrence to defense in magical confrontations.

We’re focusing on the Horn Tongue Hex, a peculiar and effective charm that transforms the target’s tongue into a sharp, horn-like object—rendering speech difficult and causing moderate magical discomfort.

This hex was first recorded during goblin uprisings and was used by wizards to temporarily incapacitate leaders mid-negotiation. That alone should tell you the spell’s power and controversy.

Spell Overview

Lingua Cornua – Horn Tongue Hex

• Incantation: Lingua Cornua
• Wand Movement: Tight zigzag followed by a jab toward the mouth
• Type: Transformation Hex
• Difficulty: Moderate
• Category: Oral Hexes

Spell Function

The Horn Tongue Hex causes the following:

• The target’s tongue becomes stiff, horn-like, and immobile
• Temporary inability to speak incantations, disrupting spellcasting
• Commonly used in duels, interrogations, and occasionally in school pranks
• Reversible with Finite Incantatem or the more specific Lingua Reverso charm

When to Use It

• During duels to prevent the opponent from casting spells verbally
• As a counter to Veritaserum-induced confessions (with ethical caution)
• In defense scenarios where stunning is ineffective
• Occasionally used by pranksters to silence gossip

Practical Scenario

During a Dueling Club mishap, a fifth-year Hufflepuff cast Lingua Cornua on her opponent mid-duel.

• The hex landed cleanly, disrupting a Stupefy incantation
• However, the tongue also emitted magical sparks due to wand core resonance
• Madam Pomfrey reversed it with a combination of Lingua Reverso and Peppermint Potion

Magical Tips

• Best used preemptively—before the target utters their spell
• Combine with Expelliarmus or Leg-Locker Curse for immobilization
• Backfire risk: If miscast, your own tongue may be affected
