Build, test, and debug regular expressions
Matches word-like sequences starting with optional word characters or apostrophes, requiring at least one letter and word character in the middle, and allowing trailing word characters or dots, plus an optional hyphenated segment. With global and multiline flags, it catches most words in text, including ones with apostrophes, periods, or hyphens (like "don't", "e.g.", or "well-known" suffixes). Useful for broad text tokenization or word extraction across lines.
