I noticed that “s” at the end of the a word is often pronounced like „s“, in case the first letter of the next word is a vowel,
Example: Desculpe, mas eu nao entendo => mas is pronounced “mas”
When there is a consonant following, then it is often a „sh“ sound.
Example: Pode falar mais devagar? => mais is pronounced “maish”.
Is that correct and is it a rule of thumb?
Thanks and obrigada
