English/Scots.  They have a common origin, and went through a long period
of separate development.  Currently, everyone who speaks Scots also
speaks English, and the languages are closely related: consequently,
there exists a dialect continuum between pure Scots and English with
Scottish accent and vocabulary.  English literature and Scots literature
continue to be independent, although people who read English can learn
to read Scots without too much difficulty.

Except that Scots is co-official in Scotland and Latgalian is not
co-official anywhere (though it is a recognized minority language),
the parallel seems complete, and if "sco" is justified, so is "ltg".

O beautiful for patriot's dream that sees beyond the years
Thine alabaster cities gleam undimmed by human tears!
America! America!  God mend thine every flaw,
Confirm thy soul in self-control, thy liberty in law!
        --one of the verses not usually taught in U.S. schools
