I am looking for a regex pattern that ensures the user puts in a single lower case word with only letters of the alphabet. Basically they are picking a subdomain. Thanks in advance

The character class
[a-z]describes one single character of the alphabet of lowercase lettersa–z. If you want if an input does only contain characters of that class, use this:^and$mark the start and end of the string respectively. And the quantifier+allows one or more repetitions of the preceding expression.
