Breakdown of Parabéns!
Questions & Answers about Parabéns!
The accent in é shows that:
- the stressed syllable is béns
- the vowel is an open é sound
So the word is stressed as pa-ra-BÉNS, not PA-ra-bens or pa-RA-bens.
Because it is plural in form. Parabéns is historically related to the idea of offering congratulations, which is also plural in English.
That said, learners should mostly treat Parabéns! as a fixed expression meaning:
- Congratulations!
- Happy birthday! in the right context
You do not normally change it to a singular form.
