Morphological Changes
Grammar Rule in 30 Seconds
Romanian verbs often change their internal stem vowels or consonants based on the stress and the following vowel.
- Vowel alternation: 'e' becomes 'ea' when stressed (e.g., 'a vedea' -> 'eu văd').
- Consonant shift: 't' often becomes 'ț' before 'i' (e.g., 'a purta' -> 'eu port' vs 'tu porți').
- Stress-based changes: Stems change shape depending on whether the suffix is stressed or unstressed.
