Here's a curiosity that has me overwrought (not wreally):

Is there some kind of relationship in the number of words in English that begin with wr- and seem to have some idea of twisting? For instance ...

wrest, wrestle, wrap, wreath, wraith?, wrinkle, wretch, wretched, wreck, wrist?, wrath, writhe, wriggle, wring, wreak?, wrangle
