Find the odd word (orthography pattern): Choose the option that does not start with the Ge- or Gi- sound and letter pattern.

Introduction / Context:Lexical classification may use orthographic onset patterns. Three options begin with the same letter sequence and closely related phonetic onset, while one begins with a different letter and sound, making it an objective odd-one-out based on spelling and pronunciation.

Given Data / Assumptions:

• Genius: starts with Ge-.
• Geyser: starts with Ge-.
• Gesture: starts with Ge-.
• Revenge: starts with Re-, not Ge-.

Concept / Approach:Group by initial orthographic cluster. Items sharing Ge- are grouped; the item with a different onset cluster is separated.

Step-by-Step Solution:

Verification / Alternative check:Phonetic onset also differs: the three share a hard or soft G with e following; Revenge begins with an R consonant cluster.

Why Other Options Are Wrong:They share the same initial letter sequence, satisfying the pattern criterion.

Common Pitfalls:Do not switch to semantics; the question tests spelling pattern, not meaning.

Final Answer:Revenge
