Rule 2.2 Ball: how the wording changed
50 rulebooks state this rule, from 1928 to 26 January 2025. The wording was reworded or changed 25 times.
How to read this page
- Added words are underlined and sit inside [+ +].
Removed wordsare struck through and sit inside [- -].- Each rulebook says in words what kind of change it is: unchanged (same wording as the rulebook it was compared with); punctuation only (only punctuation, spacing or capitals differ); moved (same wording, in another place or under another number); reworded (the sense is the same, said in other words); changed (the rule now says something different).
- A program matched each clause with the one before it. Automatic matches were made by the program alone; machine-reviewed ones were also checked by a second program. A person has not checked either, so a wrong match is possible.
