Search engine Conjugation.com announced yesterday that its “conjugation engine” is now available in a Web site that conjugates 15,000 verbs in the affirmative, interrogative, and negative forms, with all tenses and persons. That’s http://conjugation.com/.

It’s simple to use: just enter a verb and get the conjugations. There are popular conjugated verbs on the front page, too (along with some verbs generally regarded as rude — watch your filters.) I tried the verb spin.

You’ll get a results screen at the multiple tabs. It starts with the familiar past and present participle, along with indicative and imperative. Then the site gives lists of present and past indicative (“he/she/it span”), past participle, and indicative.

And that’s only on the first tab! Other tabs provide negative forms (“I will not be spinning”), interrogative, definitions of the verb, and examples. Actually the examples were the only thing I didn’t understand. Among them were straightforward sentences like “Spiders spin a fine web” but there was also “The dervishes whirl around and around without getting dizzy”. “Whirl” is a synonym for spin, of course, but even as such shouldn’t be in a list of examples for spin, should it?

The site also has a brief link list and the code for embedding the Conjugation.com engine on your own site.
