And finally, because of this firehose spray, we English speakers also have to contend with two different ways of accenting words. Clip on a suffix to the word wonder, and you get wonderful. But – clip on an ending to the word modern and the ending pulls the accent ahead with it: MO-dern, but mo-DERN-ity, not MO-dern-ity. That doesn’t happen with WON-der and WON-der-ful, or CHEER-y and CHEER-i-ly. But it does happen with PER-sonal, person-AL-ity.
What’s the difference? It’s that –ful and –ly are Germanic endings, while –itycame in with French. French and Latin endings pull the accent closer – TEM-pest, tem-PEST-uous – while Germanic ones leave the accent alone. One never notices such a thing, but it’s one way this ‘simple’ language is actually not so.
