## Clause-Aware Grammatical Linting for Technical & Academic Prose

Standard browser spellcheckers catch mistyped letters but miss structural agreement errors, dangling modifiers, and verbose nominalizations.

ZeeML’s Grammar Checker combines deterministic syntactic pattern matching with our 20-slot M33 text linter vault to correct agreement errors and tighten prose across four specialized linting modes.

## Frequently Asked Questions

### Does the Grammar Checker support academic and technical terminology?
Yes. Selecting Academic Style preserves specialized scientific, mathematical, and engineering terms while correcting surrounding clause mechanics.

### How is Proofreader mode different from Grammar mode?
Grammar mode focuses strictly on syntax and agreement rules, whereas Proofreader mode also smooths awkward transitions and wordy phrasing.

### Can I switch between US English and UK English spelling conventions?
Yes. Use the US English / UK English dialect toggle in the workstation toolbar to enforce American (-ize, -or, -er) or British (-ise, -our, -re) orthographic conventions.

### Does the linter explain why each grammatical correction was made?
Yes. Every detected error is accompanied by a diagnostic issue card below the output pane showing the original token, replacement, and grammatical rule.
