Irregular present tense verbs

So not all present tense verbs do the same thing, which makes them both interesting and frustrating!

Today I'll think about appeler and jeter

appeler does a double l variation and jeter a double t

Like this (imagine all this sung to doh a deer tune)

appeler is to call (and also s'appeler to call oneself)
j'appelle - I call
tu appelles - you call
il/elle/on appelle - he/ she / we call
nous appelons - we call
vous appelez - you call
ils/ elles appellent - they call

and  then jeter to throw

je jette - i throw
tu jettes - you throw
il/elle/on jette - he/ she throws /we throw
nous jetons - we throw
vous jetez - you throw
ils/ elles jettent - they throw

So you see, the nous and vous forms look like the infinitive and all the other parts change!
