I saw this two days ago in a news article about a new mobile phone.

Problems:
1. A word is misspelled.
2. A hyphen is missing.

Explanation:
The news article was about the BlackBerry Storm.

One of the Web pages in the article discussed the data-related features of the Storm.

While discussing the data technology, the article author wrote “The smart phone operates on Verizon Wireless’ 3G EV-DO Rev A. network in the U.S., promising lightening quick data rates and Internet surfing.”

First, while trying to play on the “Storm” model name, the author misspelled “lightning” as “lightening”.

I believe that this first problem relates to sloppy pronunciation of the noun “lightning”.

Second, while trying to modify “data rates” to indicate a high speed, the author failed to put a hyphen between (sic) “lightening” and “quick”.

I suspect that this second problem relates to a general decline in skill with hyphenation.

Solution:
“… promising lightning-quick data rates …”
