There are many categories of Spanish verbs as you can see in our different webpages. This lesson will focus on verbs that are called “defective” or “incomplete” because they do not have all the personal forms or tenses as most verbs do. On this page you will learn which are the most common defective verbs, and about two subcategories: impersonal and bipersonal verbs. Use the exercise below to practice the use of defective verbs in Spanish.

In general, defective verbs do not have complete conjugation due to the fact that they lack some personal forms or some tenses.

Impersonal verbs

These verbs are only conjugated in the third person singular form, and in general they refer to nature and weather.

Bipersonal verbs

These verbs are only conjugated in the third person singular and the plural.

Examples of bipersonal verbs in context

• Llovió esta mañana en toda la ciudad. It rained all morning throughout the city.
