Common Mistakes to Avoid

⚠️

Suffix position with punctuation

Solution: "hello, world" with suffix "!" might become "hello,! world!" - punctuation handling varies by tool.

⚠️

Irregular plurals

Solution: Adding "s" for plurals doesn't work for irregular words: "child" → "childs" (wrong). Handle manually.

⚠️

Double suffixes on some words

Solution: If words already have the suffix, you get doubles: "file.txt" → "file.txt.txt". Filter first.
