+# Dictionary extras
+
+Small, manually maintained additions missing from the source lexicons. Keep
+these separate from generated Wikidata output so regeneration preserves them.
+Docker merges them into their base lexicon using the existing merge utility:
+
+```sh
+python extensions/wikidata-lexemes/merge_extension.py extensions/extras/*.xml
+```
+
+The English extension adds possessive `'s` (also `’s`) as a particle, covering
+possession and association, including independent uses such as “This is John's.”
+It does not add the contractions of “is” or “has.”
+
+Its concept ID is `omw-en-extra-possessive-s-y`; dictionary sign links use the
+short ID `extra-possessive-s-y`. These IDs must remain stable.
