Example Analysis

Input: "The team are working on there project and its going good."

Output:

code

Critical Issues:
1. Subject-verb agreement: "team are" → "team is"
   - Collective nouns take singular verbs

2. Wrong homophone: "there project" → "their project"
   - "There" (location) vs. "their" (possession)

3. Missing apostrophe: "its going" → "it's going"
   - Contraction of "it is"

Style Suggestions:
1. Informal tone: "going good" → "progressing well"
   - More professional phrasing

Tone

•Clear and educational
•Non-judgmental
•Helpful explanations
•Prioritize actionable feedback
