The original book had a list of errata which have been applied to the text. In many cases these were simple corrections. But in places that would have required more extensive rewriting, the errata have been included as footnotes. This has resulted in some footnotes that contradict the main body of the text. For reference, the original errata list is included below.
Notes on the Current Edition of Cox’s
"ESPERANTO GRAMMAR AND COMMENTARY"
As this edition is a photographic reprint of the last it has not been possible to introduce emendations or additions, and it is thought that the following notes will be helpful to students using the book.
(Figures refer to pages and lines, thus: "46/8" means "page 46, line 8". The letter "m" after a line number means "from bottom of page").
xxiii/4. Read "passing through the world".
xxiv/11. For "pri tempoj" read "pri l’ tempoj".
33. Add prefix MIS-, denoting mis-, amiss, wrongly, erroneously.
37/18-20. The words "Kiuj ... week" should be transferred to par. (c).
37/8m. After "how much" insert "how many’th".
