Spanish language Q&A Forum

In Kwiziq, there's a lesson on -ito etc and a lesson on -illo etc. I'm living in Ecuador and have traveled around Central and South America a bit, and I've heard both groups of suffixes used in what seems to be the exact same way. I guess I'm looking for a little clarity on whether they are 100% interchangeable. 

Am I correct that team -ito and team -illo mean the same thing - they make a word diminutive, softer, affectionate - and that the real difference is just in local usage? I can use either group of suffixes, and not be wrong, but one group is just more common in certain areas than the other?

My apologies if you've answered this elsewhere. I reviewed the other questions, and I did not find an answer that makes me confident that my understanding is correct.

And thanks, in advance for your help.

Thanks!

I am having difficulty understanding when an answer is simply incorrect and you wouldn't say it in Spanish, and when the answer given is not what Kwiz expects to see.   For example, I wrote 'Cuando fine la leccion' (I can't find the accent!) and it was marked incorrect.  Would it be incorrect to say that in conversation with a Spanish speaker?

Many thanks

Hola…..¿por qué se usa el imperfecto de subjuntivo con una oración que empiece con “No sabía que_________”.  No entiendo el “trigger” en este caso.

I reported this as an issue, and perhaps should have brought it up here instead. For one of the quizzes, the answer is 

A veces __me olvido de__ que llevamos casados 20 años. (Sometimes I forget that we've been married for 20 years.)

I noticed that the verb *olvidar* is being used intransitively and that, even though the "accidental se" is being used, that olvido is not in the third person. (It's not in the preterite / no accent on the o). I'm having trouble finding an example of this on the lesson page. 

Thanks!
