Infinitives

The infinitive is the part of the verb you will find most commonly listed in dictionaries. It names a particular activity without saying when it happens – in other words, it only explains what is being described. It cannot show number, mood, time or person. It is best translated into English with the word ‘to’ – to speak, to show, to break, to cook etc.

In Spanish, the infinitive will end in one of three ways: -ar, -ir or –ir. In some cases, such as reír (to laugh) or freír (to fry), the vowel takes an accent.

Here are some random examples: abrir (to come), llegar, (to arrive), comer (to eat).
