Mixing up Obstruir and Tapar

For verbs like 'obstruir', when the 'u' sound meets another vowel, Spanish adds a 'y' to keep the pronunciation strong. This is why we say 'obstruyo' instead of 'obstruo'.

The 'Y' Rule

In the past tense (preterite), the 'i' changes to 'y' for 'él/ella/usted' (obstruyó) and 'ellos' (obstruyeron) to avoid having three vowels in a row.

Spelling Change in the Past

Use this word when you want to sound a bit more professional or serious, like in a news report or a doctor's office. For everyday chores, 'tapar' or 'atascar' is more common.

When to use 'Obstruir'

Commonly used in medical, technical, and traffic contexts.

Using 'obstruir' for people

Just like in English, physical words are often used for ideas. 'Obstruir' works for both a pipe and a court case.

Abstract Usage

This figurative use is very formal. You will mostly see it in newspapers or official documents.

Formal Contexts

Common in legal and political discussions.

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.
