The Five Vowels (A-E-I-O-U)
Grammar Rule in 30 Seconds
Filipino uses five pure, consistent vowel sounds (A, E, I, O, U) that never change, unlike English vowels.
- A sounds like 'ah' as in 'father' (e.g., 'ama').
- E and I are distinct; E is 'eh' (bed), I is 'ee' (see) (e.g., 'ito').
- O and U are distinct; O is 'oh' (go), U is 'oo' (moon) (e.g., 'ulo').
