Question

Why are there two different formations of agradable?

---

agradabilísimo y agradablísimo

Is there a different meaning or reason there are two different versions?

the second form you show is a typo - pacofinkler, Jul 24, 2013

Thank you. I found 1 site that had it spelled the same b4 I submitted this inquiry. http://quizlet.com/16912989/irregular-superlatives-flash-cards/ On slide 6 of 9 there it was. Spelled exactly the same but that was the only other place I could find that - kev-ace, Jul 24, 2013

Answer 1

As far as I know, the correct form would be: agradabilísimo

Answer 2

I have never known of any set of grammar rules governing the structure of superlatives and diminutives - kind of like slang - so you can say it any way you choose, ie: agradabilísimo / agradablísimo / agradablezón / agradablesísimo, etc.

And although you might be able to say that last one, I´m pretty sure I can´t ;) - rogspax, Jul 25, 2013

I find it hard to believe that the responsible grammar nerds haven´t come up with a set of rules. Isn´t that what they do? ;) There are a lot published, including there on SD, but I don´t know what is authoritiative, and RAE often just makes my head spin - rogspax, Jul 25, 2013

Again, I have never seen any rules, but how can there be any? In Mexico we say "ito", in Spain "illo", in PR "ico". No matter which you choose, you will always be understood perfectly. - 005faa61, Jul 25, 2013

Answer 3

I rather think that agradablísimo is the correct one. It is one of a fairly small list of irregular superlatives.

I went back and found this, confirming, after I started to doubt myself.

irregular superlatives

So, I don´t think there are truly, officially, two forms, but rather than the one is an incorrectly (though regularly) formed version of an irregular superlative, akin to goodest.

I don´t believe this is an issue of a tilde, which I believe my choice has properly, but rather the spelling. But I find myself on little sleep yet again, so I may be confused and-or confusing. - rogspax, Jul 24, 2013

note the total number of ´i´-s in the correct version. - rogspax, Jul 24, 2013

Check the tilde it makes a difference. - pacofinkler, Jul 24, 2013
