You're probably looking for something like ([A-Z]\w ) This will match any uppercase word with 0 or more single uppercase letters within.

Use a website like regex101.com to adapt/build your own regex expression. It's a handy thing to know

If you want a regex that matches a word that contains an uppercase character you could use:

\S [A-Z]\S 

• \S matches any non-whitespace character
• matches at least one of the previous capture group
• [A-Z] matches any character between A and Z (all uppercase characters)

So this regex matches non-whitespace characters that contain an uppercase character. Note that this will match:

• regEx
• RegEx
• REGEX

It will not match:

• regE
• Regex
• reg Ex
