There are several issues in complex commands descriptions.

*if command*
>
> if list then list [ elif list then list ] ... [ else list ] fi
>               The  if list is executed, and if it returns a zero exit
> status, the then list is executed.  Otherwise, the elif list is executed
>               and if its status is zero, the then list is executed.  If
> each elif list returns nonzero status, the else list is executed.


There is no mention of a terminator after *list*. It's better to rewrite
command description as:

if list *term* then list *term* [ elif list *term *then list *term *] ... [
> else list *term *] fi

              The  if list is executed, and if it returns a zero exit
> status, the then list is executed.  Otherwise, the elif list is executed
>               and if its status is zero, the then list is executed.  If
> each elif list returns nonzero status, the else list is executed.


*for command*

>        for name ... [ in word ... ] term do list done
>               Expand the list of words, and set the parameter name to each
> of them in turn, executing list each time.  If  the  `in  word'  is
>               omitted, use the positional parameters instead of the words.
>               The term consists of one or more newline or ; which
> terminate the words, and are optional when the `in word' is omitted.
>               More  than one parameter name can appear before the list of
> words.  If N names are given, then on each execution of the loop the
>               next N words are assigned to the corresponding parameters.
> If there are more names than remaining words, the remaining  parame‐
>               ters  are each set to the empty string.  Execution of the
> loop ends when there is no remaining word to assign to the first name.
>               It is only possible for in to appear as the first name in
> the list, else it will be treated as marking the end of the list.

It's better to write at my glance:

>        for name ... [ in word ... ] term do list *term* done
>               Expand the list of words, and set the parameter name to each
> of them in turn, executing list each time.  If  the  `in  word'  is
>               omitted, use the positional parameters instead of the words.
>               The term consists of one or more newline or ; which
> terminate the words, and are optional when the `in word' is omitted.
>               More  than one parameter name can appear before the list of
> words.  If N names are given, then on each execution of the loop the
>               next N words are assigned to the corresponding parameters.
> If there are more names than remaining words, the remaining  parame‐
>               ters  are each set to the empty string.  Execution of the
> loop ends when there is no remaining word to assign to the first name.
>               It is only possible for in to appear as the first name in
> the list, else it will be treated as marking the end of the list.

The same issues applies for:

   - for (second form)
   - while
   - until
   - repeat
