Irregular Imperatives

A student learning Latin will come across early on five words with irregular imperatives: nolo, dico, duco, facio, and fero. Of these, the latter four are missing a vowel for the imperative singular. So, whereas 3rd conjugation verbs have a short e ending, these words lack it. There is, however, a little mnemonic device to memorize them:

dic, duc, fac, fer, drop the e and you'll find it there.

I've also seen it something "and you'll be there" vel sim. I'd prefer the former since you're not actually going anywhere, but finding the right form of the verb!

Thanks to my high school Latin teacher Ryan Sellers for this one. I never forgot it.

I also found this on YouTube, which some teachers may wish to use to be more creative in their classrooms:

I'm not sure exactly what these words are, but a creative interpretation would be:

Dic, duc, fac and fer / these four words are irregular;
Dic, duc, fac and fer / should have an e but it isn't there.

In my opinion, the first is easier to memorize, though I guess you cannot beat singing it!
