Don't use it for 'to change clothes'

'Alterar' often implies changing the essence or the natural state of something, whereas 'cambiar' is more general. Think of 'alterar' as 'to tinker with' or 'to disrupt'.

Using Alterar vs. Cambiar

Use 'alterar' when you want to sound slightly more formal or precise about a change that might have a negative impact on a system.

Natural Sounding Tip

Very common in both spoken and written Spanish for talking about changes or modifications.

Getting upset vs. Being angry

When someone gets upset by themselves, we often use the reflexive form 'alterarse'. For example: 'No te alteres' means 'Don't get yourself worked up'.

The Reflexive Form

If you see a sign that says 'No alterar el orden público', it means 'Do not disturb the peace'.

Context Tip

Very common when describing emotions or being upset.

Don't say 'con'

In this context, the thing being changed (the document, the evidence) is always the direct object of the action. You don't need a preposition like 'with' in Spanish.

The object of 'Alterar'

This is a serious word in legal contexts. Use 'modificar' if the change is authorized and 'alterar' if it's suspicious or unauthorized.

Legal Language

Common in legal, scientific, or formal contexts.

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.
