"She is the worst student."

Translation: Lei è la studentessa peggiore.

[benczurp]

She is the worst student -- studentessa peggiore. But how you differentiate between "she is the worst female student" from "she is the worst overall"?
Surely you can use different solutions -- but within this framework?

[HaroldWonh]

And why not "la piu peggiore"? Isn't it possible to distinguish between "worse" and "worst"?

[cptwunderlich]

Because "peggiore" is the irregular comparative of "cattivo/a" - "bad". The regular comparative is "cattivo, più cattivo, il più cattivo and cattivissimo". Some adjectives have also an irregular form, like here, which is "cattivo - peggiore - pessimo"
See: http://it.wikipedia.org/wiki/Grado_di_comparazione#Comparativi_e_superlativi_particolari

What I don't understand is, is it "la peggior studentessa/la studentessa peggiore" and therefore "la peggiore", a "Superlativo relativo"? Why not "pessimo"/"pessima"?

[Maisie07]

I agree, the sentence asks you which is the worst, not the worse. So why is piu peggiore wrong?

[IsolaCiao]

Peggiore means worse and worst, depending on how it's used in a sentence. When we use the definite article, "la studentessa peggiore", it means the worst student.

Thanks for clarifying that :)

Was wondering the same thing. Reporting....

Why "peggior" instead of "peggiore"?

[ZoranMilokanovic]

I've got the same question. When does peggioRE contract to peggioR? Many thanks.

[AaronDandr]

In this case the most correct sentence is "Lei è la studente/studentessa peggiore", the duo's sentence is the worst sentence possible and in part is wrong because in italy we don't use "lo" for a female subject

lei è la peggiore studente not accepted. Reported 19 July 2017

[IsolaCiao]

studente is masculine, so you can't use la with it

[Jeffrey855877]

Ah, I've undone myself once again by studying Spanish as the same time, where el/la estudiante is mf, depending on the article or adjective used.

[dfjacobs]

I would like to study Spanish but don't because I know I would confuse it with Italian. Native Spanish speakers I know can actually understand Italian pretty well.
