How can I make

the 'c' file because of the substring(@word, 1,1) filter.
What happens with
<xsl:for-each-group
select="Word"
group-by="lower-case(substring(@word,1,1))"
collation="http://saxon.sf.net/collation?lang=cs">
?
substring() counts Unicode codepoints, not collation units, so if the
word starts with 'ch', it will return 'c'.
