What do these changes do

Systematically improved English language quality across 45+ files including documentation files (markdown, RST) and Python docstrings: grammar fixes, consistent terminology, clearer word choice, removed verbose phrasing, and updated outdated references.

What was wrong

Documentation and Python docstrings contained grammar errors (plural/singular mismatches, incorrect verb forms), inconsistent terminology (setup.py vs pyproject.toml), missing hyphens in compound adjectives, verbose phrasing ("This function" pattern), typos, and awkward phrasing that reduced clarity for non-native English speakers.

How this fixes it

Documentation files (15 files):

Grammar corrections:

• Verb agreement: "who are using" → "who is using", "pledge to making" → "pledge to make"
• Singular/plural: "codes" → "code", "dependency" → "dependencies"
• Compound adjectives: "AI assisted" → "AI-assisted", "Commented out" → "Commented-out"

Consistency improvements:

• Updated setup.py references → pyproject.toml (reflects current project structure)
• Fixed step numbering in release.md (was 0,1,3,4... now 0,1,2,3...)
• Standardized formal examples: "like" → "such as"

Clarity enhancements:

• Removed redundant phrasing: "on both X and also Y" → "on both X and Y"
• Fixed table formatting in corpus_license.md
• Broke up overly long sentences in docs/notes/start.rst
• Clarified obsolete status in tokenization-benchmark.md

Python docstrings (30+ files across core modules):

Removed verbose phrasing:

• "This function converts..." → "Converts..."
• "This function will detokenize..." → "Detokenizes..."
• Applied to tokenize, spell, word_vector, wsd, transliterate, summarize, soundex, and util modules

Fixed grammar and typos:

• "the word is that mostly unrelated" → "the word that is mostly unrelated"
• "list of words are" → "list of words is"
• "incurs an edit distance" → "have an edit distance"
• "repiitition" → "repetition"
• "fits" → "fit", "map" → "maps", "stopword" → "stopwords"

Improved clarity:

• "This function will call reorder_vowels() first, to make sure that..." → "Calls reorder_vowels() first to ensure that..."
• Standardized article usage and verb forms throughout
• Enhanced professional tone across all docstrings
