Spanish pronunciation tip

5년 전

In spanish,  A (pronounced as in Father),  E (pronounced as in Set), O (pronounced as in Open), are strong vowels and I (y) (pronounced as in Machine), U (pronounced as in Rule)  are weak vowels. 

Two strong vowels cannot stand together in one syllable. 

De-se-o, De-se-ar, I-de-a, Te-a-tro 

A strong and a weak vowel, or two weak vowels together, form a diphthong and can be together.  

Due-ño, Rui-do, Siem-pre 

If the weak vowel bears a written accent, they have to be separated.

Le-ído, rí-o, pa-ís, Ma-rí-a
