I'm certainly no expert on domains, but while short's nice, exactly what is the opportunity with a non-business dictionary? That's where you'd have to start.
If it's 'branding', as in, a business could do booming business off of a short domain, well, they can build a brand on anything (bell, telus, google, yahoo). So I don't think that increases the value.
Personally it's not one I'd pick up. I suspect that it's more of a domain speculator type domain - buy it and hold for 15 years under the hope that someone will want to pay big bucks for one of your many domains, thus paying for all of them + profit.
But again, I'm no expert
