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