Spelling – Identify the one misspelled word among options A–D, or choose “All correct” if every option is correctly spelled. A) Deploy B) Emply C) Supply D) Reply

Introduction / Context:
This item examines vowel omission errors in common verbs ending with “-ply/-ploy”. Only one option removes an essential vowel, creating a nonword that looks plausible at a glance.

Given Data / Assumptions:

• Options: Deploy, Employ, Supply, Reply (given “Emply” for Employ).
• Orthographic pattern: “ploy” vs “ply” endings with distinct prefixes.

Concept / Approach:
Recognize base verbs and prefixes: de-ploy, em-ploy, sup-ply, re-ply. The odd one out is “Emply”, which is missing “o” and should be “Employ”. Others are standard spellings.

Step-by-Step Solution:

Verification / Alternative check:
Pronunciation cue: /ɛmˈplɔɪ/ requires the “oy” digraph; without “o”, the pronunciation breaks. Dictionaries list only “employ”.

Why Other Options Are Wrong:

• Deploy: Correct.
• Supply: Correct.
• Reply: Correct.

Common Pitfalls:
Typing omission with consonant clusters (mp + l) leads to lost vowels in fast writing. Always check digraphs “oy/oi”.

Final Answer:
Emply
