There are three basic types of stem-changing verbs.

First things first: there are three classes of Spanish verbs: -ar verbs, -er verbs, and -ir verbs. These are the infinitive verb endings (or dictionary form of the verb).

Some verbs have an irregular -go ending for the yo form in the present tense:

• e-ie stem-changing verbs: verbs in which an e in the stem changes to an ie.
• e-i stem-changing verbs: verbs in which an e in the stem changes to an i.
• o-ue stem-changing verbs: verbs in which an o in the stem changes to a ue.

Irregular “yo” form with no stem change

• conocer – “to know” – yo conozco, tú conoces.
• dar – “to give” – yo doy, tú das.
• hacer – “to do, make” – yo hago, tú haces.
• poner – “to put” – yo pongo, tú pones.
• salir – “to exit” – yo salgo, tú sales.
• traer – “to bring” – yo traigo, tú traes.
• ver – “to see” – yo veo, tú ves.

Verbs in Spanish that are completely regular in the present tense except for the yo form are called yo irregulars . There is an entirely new tense called the present subjunctive. Verbs with a similar irregular yo form are grouped together to help you remember them. …

There are a number of Spanish verbs which are regular in the present tense in all but the first person singular. These are known as “g verbs” or “yo go verbs” because the first person singular requires an unexpected g and the conjugation then ends in -go.

An infinitive verb is essentially the base form of a verb with the word “to” in front of it. When you use an infinitive verb, the “to” is a part of the verb. It is not acting as a preposition in this case.

) is the most basic form of a Spanish verb. Verbs in the infinitive form are not conjugated and do not indicate anything about who is performing an action or at what point in time the action is taking place.

Any verb that is preceded by the word ‘to’ is an infinitive. Here are some examples: ‘to love, to eat, to run, to believe, to follow, to laugh, to stare, to wonder.

Make sure you are looking at an infinitive and not a prepositional phrase by viewing the word or words that appear after the word “to” in the sentence. If the word “to” in the sentence is followed by a root-form verb, it is always an infinitive.

An infinitive is formed from a verb but doesn’t act as a verb. It acts as a noun, adjective, or adverb, and it is actually made up of two words: to + verb. These two words act together as a noun, adjective, or adverb. Words that are formed from verbs but don’t act as verbs are called verbals.

The infinitive form of a verb is the verb in its basic form. It is the version of the verb which will appear in the dictionary. The infinitive form of a verb is usually preceded by “to” (e.g., “to run,” “to dance,” “to think”). (The infinitive form with the word “to” is called the “full infinitive” or “to-infinitive.”)

Gerunds and infinitives can replace a noun in a sentence. Gerund = the present participle (-ing) form of the verb, e.g., singing, dancing, running. Infinitive = to + the base form of the verb, e.g., to sing, to dance, to run. Whether you use a gerund or an infinitive depends on the main verb in the sentence.

A gerund is the –ing form of a verb that functions the same as a noun. For example, “Running is fun.” In this sentence, “running” is the gerund. It acts just like a noun.

Following a verb (gerund or infinitive) Both gerunds and infinitives can replace a noun as the object of a verb. Whether you use a gerund or an infinitive depends on the main verb in the sentence.

There are no categorical antonyms for gerund. (In English, a gerund has the same spelling as a present participle, but functions differently.)

One way to spot a gerund is to notice that they always end in -ing. Just remember they’re not the only players in the game ending in -ing. Present participles (verbs indicating continuous activity) also end in -ing. For example: “I was sitting there.” Sitting looks like and acts like a verb in this instance.

Yes, gerunds all end with -ing, simply by definition. A gerund is, in Latin, a form of the verb which can be construed as (i.e. has functional characteristics of) a noun – it can act as subject or object of a verb, for example, or can take a plural ending.

The easiest way to tell the difference between the gerund and the present participle is to look for the helping verb “be”. If you find a form of “be” followed by the -ing form, that’s the present participle. For example: They’ve have been working for four hours.

A verb ending in -ing is either a present participle or a gerund.

Dying is the gerund or progressive form of the verb die, meaning to expire or to cease to live.

Dieing is a misspelling if you are referring to death. The past participial form of die (death) is irregular, so you use dying. However, there is a specialized instance when you might use dieing and it be correct. There is a machine called a die-cut machine that cuts out shapes, letters, and numbers from paper.

Verb Forms of Die

If you are referring to death, the verb you have in mind is most likely dying. Dying is the present participle of die, i.e., to cease living. For example, Soldiers are dying for their country.
