The Prefix "Co-"

The Prefix "Re-" Reading The Prefix "Co-" 1 minute Next The Language of a Text

The rule is to add the prefix to the front of the word and make a solid word. The prefix "co-" has generally been an exception to this rule and has been hyphenated. I would say that it is "in transition." That is, it is generally moving toward being made a solid word in many instances.

The problem, as I see it, is that many of the combinations are hard to read.

...He is a codefendant.
...He is a cosponsor.

Fairly ugly!

For the sake of readability, I would continue to hyphenate those that are hard to read.

Happy punctuating!
