Thanks, see a few comments below.

That newline before the closing quote is redundant,

> point.

The first sentence of a doc string should preferably mention the
mandatory arguments (TYPE and ARG).  If the result is too long to fit
on a single line, consider saying only the main part there, and then
describing the details in the following lines.

> +TYPE of abbrev includes \"Global\", \"Mode\".

"Includes"? are there other types?

>  (defun inverse-add-abbrev (table type arg)
> +  "Define the word before point as as an abbrev in TABLE.
                                   ^^^^^
Typo.

> +ARG means use the ARG-th word before point as the
> +abbreviation.  Negative ARG means use the ARG-th word after point.
