Hyphenation like this is optional.
By default, portable infoboxes will try to fit in as much text as possible on any given line, and then break words with a hyphen when it reaches the end of the line. If you're a part of a community that doesn’t like this method of line-breaking, it’s easy to turn off.
.portable-infobox .pi-navigation,
.portable-infobox .pi-header,
.portable-infobox .pi-caption,
.portable-infobox .pi-data-value,
.portable-infobox .pi-data-label {
-webkit-hyphens:none;
-moz-hyphens:none;
-ms-hyphens:none;
hyphens:none;
}
But even though you can turn it off, you might not find it makes that much difference to how many lines are used to accommodate your text. In fact, in some instances, turning off hyphenation could make your total line usage increase.
