Forgetting the Stem Change

Using the Wrong Preposition

The verb 'comenzar' is irregular. When you use 'yo,' 'tú,' 'él/ella/usted,' or 'ellos/ellas/ustedes' in the present tense, the 'e' changes to 'ie' (e.g., c**o**m**ie**nzan). The 'nosotros' and 'vosotros' forms stay regular (c**o**m**e**nzamos).

Stem Change Alert

If you want to say 'to start DOING something,' you must put the word 'a' before the next verb: 'Comienzan a hablar' (They start to talk).

When to use 'a'

In 'comienzan,' the stress falls on the syllable 'mien' (koh-mee-EHN-sahn), which is typical for these stem-changing verbs.

Pronunciation Tip

Extremely common. This is the standard way to say 'they start' or 'you (plural formal) start' in the present tense.

When 'comenzar' is followed by a reflexive verb (like sentirse), it describes the start of a personal or emotional state, focusing on the internal experience of the subjects.

Action vs. State

Used to describe the initiation of a mental or emotional state, or a gradual process.

'Comienzan' means 'they begin' or 'you (plural formal) start.' Learn its irregular E→IE stem-changing conjugation, how to use it with 'a' for actions, and compare it with 'empezar'.

Test your knowledge with interactive exercises

Verb conjugation is the backbone of Spanish communication. Every sentence you speak or write requires at least one conjugated verb, and getting it right determines whether you sound fluent or confused.

The good news: Spanish has clear patterns. Regular -ar, -er, and -ir verbs follow predictable rules, and the 20 most common irregular verbs cover the vast majority of everyday conversation. Master those, and you''re already ahead of most learners.

Past, present, future, hypothetical — conjugations let you place actions exactly when they happened or might happen.

Wrong conjugations can change who did what. ''Hablé'' (I spoke) vs ''habló'' (he spoke) — one accent mark, completely different meaning.

DELE, AP Spanish, and university placement tests all heavily test conjugation accuracy. It''s the most testable skill in Spanish.

When conjugation becomes automatic, you stop translating in your head and start thinking directly in Spanish. That''s true fluency.

Spanish has 14 major verb tenses across 3 moods (indicative, subjunctive, imperative), but just 3 tenses — present, preterite, and imperfect — account for over 80% of verbs used in everyday speech. Focus there first.
