    I was at Lynda.com and I just watched “dynamically fixing orphaned words with GREP by Michael …something, sorry. in it, he uses the term (?<=ws(?+w+[[:punct:]]+$). In an earlier course he described the + (one or more) modifier as unusable in a lookbehind or lookahead i.e. (?<=.+). what's the difference here?

    Hello

    Are you sure about the regular expression ? I think it is (?<=w)s(?=w+[[:punct:]]+$)

    In a lookbehind, the string must have the same length, i.e. the same number of characters. You can't use + * or ?

    ex : (?<=figs?)d is impossible (matche a digit preceded by fig or figs)

    There is no limitation in a lookahead.
