Say I have this query...

SELECT ?human ?label
WHERE
{
  ?human wdt:P31 wd:Q15632617; rdfs:label ?label.
  FILTER(LANG(?label) = "en").
  FILTER(STRSTARTS(?label, "Mr. ")).
}

What if I wanted to see if any one of a humans name ends with "y" such as my last name does , their first, last, doesn't matter.  I have a "d" and a "y" on the array returned from my name (if it were split by whitespace)

I did not see any special syntax or FILTER or Label service commands to help with splitting apart a Label by whitespace and then applying a filter on each string.
