To validate only word simplest regex would be (I think)
/^\\w+$/
I want to exclude digits and _ from this (as it accept
^(?!.*(?:p|k))[a-zA-Z]+$
This should do it.See demo.The negative lookahead will assert that matching word has no p or k.Use i modifier as well.

var re = /^(?!.*(?:p|k))[a-zA-Z]+$/gmi;
var str = 'One\nTwo\n\nFour\nFourp\nFourk';
var m;
while ((m = re.exec(str)) != null) {
if (m.index === re.lastIndex) {
re.lastIndex++;
}
// View your result using the m-variable.
// eg m[0] etc.
}
