[Regex Expression] Tagline --- {0, } {1,10}

Using a character set repeated 1 or more times, make a pattern to search for strings that do not contain the characters ‘a‘, ‘e‘, ‘i‘, ‘o‘, ‘u‘, and ‘y‘.

/[^aeiouy]+/gi

Next, surround our pattern with a word boundary on each side.

/\b[^aeiouy]+\b/gi

But wait, our pattern is considering strings containing white space to be misspelled words. Add the white space to the characters we wish to not match.

/\b[^aeiouy\s]+\b/gi
