Answer 1

^ stand for start of string
[A-Za-z] stand for one occurence of any of char range
\w stand for word char (ie: any alphanumeric char, including underline char)
{7,14} specify than previous \w need to be found between 7 and 14 times
$ stand for end of string (in some context, also mark new line)
