There's no direct translation to this. Like, there's no "it" in Portuguese, there's no "-se" in English. So, naturally, it is not an easy concept do be understood. Atualmente, fala-se muito sobre o aquecimento global. - Nowadays, there's much discussion about global warming. Vende-se carro! - The car is on sale. Devemos nos perguntar... (We should ask ourselves...) Devemos se perguntar (native speakers do this sort of errors a lot, and it's a pain in the ear) Another example: Droga, eu se ferrei. (Dammit, I screwed myself - This is wrong!!!) Droga, eu me ferrei ! << this is ok >> Para se obter este item será preciso pagar um preço caro por ele. (Para obter-se este item) Wrong! Here -se must come in front of the verb) This happens when the verb is followed of adverbs like para and que, specially que. que se deve, que se supõe, que se faça, que se ame, que se queime, que se realize, que se sonhe.. You can say like... We must work hard in order we can have success. Devemos trabalhar duro para que tenhamos sucesso. É preciso trabalhar duro para que se tenha sucesso. É preciso trabalhar duro para se obter sucesso. I know it's a hard concept for non-natives but, you should not to worry about this you should keep learning portuguese 'cuz this willl flow naturaly some time ~ likewise it did to me with the particle it :)

I would like to know about the context you find the world 'SE'. Please, try to write in Portuguese, because there are rules about 'SE'.I am sure you'll find native speaker who can help you. Good luck.

I previously had a similar concern to what you have posted here, and thus you may refer to my posted question as given in, http://www.italki.com/answers/question/60855.htm In the best chosen answer, the respondent has given the explanations. In summary, such contraction between the direct/indirect object complement and the conjugated verb is already out of use, at least in modern Brazilian Portuguese. Thus, my personal suggestion is that, you may follow the same rules as in Spanish, where this kind of contraction happens only in the affirmative imperative mood, in which the present subjunctive is adopted as the respective tense. However, in imperative, we speak in the same way as it is written (at least for Spanish, as far as I know). Additionally, the expression "palavra-se" does not make sense, because "palavra" is a NOUN meaning "word" in English. My guess is that you possibly want to express the verb "palavear", which means "to chat", and so, "se palavreia (old use: palavreia-se)" would mean "to chat each other". --- Good day. / Que tenhas um bom dia. / 祝 是日安好。

Word/particle "se" has several meaning and uses in Portuguese. Actually, "se" is grammaticaly classified as a reflexive pronoun and its position may vary depending on the use of precedent words.. In English, a reflexive pronoun is always placed after the verb: To cut himself (Cortar-se), Imagined herself (Ela imaginou-se) and so on. However, in Portuguese there are three positions of the "se" particle. Próclise (pronoun placed before the verb): Nada se compara a uma boa refeição. Nothing compares a good meal. Particle "se" is placed before to the verb "Comparar". Obviously, there are many grammar rules about "se" and different cases to be observed and followed. You can Google the following terms to have a wider view on its usage: "próclise" "ênclise" "mesóclise" If you can't type portuguese accents characters on your keyboard, you can type those terms without accents. I hope I may be useful to you. Thank you.
