Is x always pronounced like sh sound?
There are no rules either....
Some use SH: Peixe, caixa
Some use Z: Exame, Executar
Some use KS: Anexo, taxi
Some use SS: Exceção, Máximo
Yes... it's not just Englosh that's hard to learn the pronunciation. As long as you practice, you will that it is not that difficult. Some sounds are better than others! =)
How is the first syllable of "come" pronounced? When you hover over the word she seems to pronounce it 'quo', but in the context of a sentence she pronounces it 'co'. Or am not hearing her correctly.
"co" has always a /k/ sound.
