Is a list of one item still a list?

Greetings All,

I was recently reviewing a document and was reminded of a rule I learned in
English class when creating a list or sublist.  That is, an ordered list
(alphabetic, or numeric) must have more than one item.  We were not allowed
to create a list with an item "A." without there also being (at least) a
"B." , or a sublist with roman numeral "i" unless there was also an "ii".

If we had only one item to discuss, we would have to make it part of the
preceding sentence.  I assume the same rule applied for bullet lists as
well.

Does this rule apply for Amharic writing and in other Ethiopic writing
practices?  That is, can a list in Amharic contain only one item?

thanks,

-Daniel
