With    a-zA-Z   you only check the first character       Assert position at the beginning of the string  a-zA-Z   Match a single character present in the list below    a-z  A character in the range between  a  and  z  A-Z  A character in the range between  A  and  Z     If you want to check if all characters are letters  use this instead      a-zA-Z     test str         Assert position at the beginning of the string  a-zA-Z   Match a single character present in the list below       Between one and unlimited times  as many as possible  giving back as needed  greedy  a-z  A character in the range between  a  and  z  A-Z  A character in the range between  A  and  Z      Assert position at the end of the string  or before the line break at the end of the string  if any    Or  using the case-insensitive flag i  you could simplify it to     a-z    i test str     Or  since you only want to test  and not match  you could check for the opposite  and negate it       a-z  i test str
