Future Perfect Continuous In English

The future perfect continuous is a verb form that combines characteristics of the future continuous (about an action that was being performed) and the future perfect (an action that was completed). Thus, we use the future perfect continuous in English to talk about an action that will be taking place in the future and will be interrupted when another action or some condition interrupts it.

Rules and uses of the future future continuous in English:

Affirmative. The basic form of the future perfect continuous is formed by the auxiliary forms of the future will or shall, followed by the simple form of the verb to have (have), followed by the participle of the verb to be (been) and the gerund of the verb that expresses the action:

Subject + will + have + been + verb in gerund (ing)

Subject + shall + have + been + gerund verb (ing)

In the case of using the auxiliary form going to, we will use the present tense of the verb to be (am, is, are) followed by going to, then the simple form of to have, the participle of to be and the gerund of the verb:

am + going to + have + been + gerund verb (ing)

is + going to + have + been + gerund verb (ing)

are + going to + have + been + gerund verb (ing)

We use it to talk about an action that is already being done and continues in the future and until it is interrupted by another action or because of some condition.:

Next Friday, Brenda will have been working in the project for three months.

They shall have been running until dinner’s time.

We use it to talk about an action that will be carried out in the future until it is interrupted by another action or because of some condition:

Mike will have been studying all the week for that test.

Susan is going to been sweeping until the rise to receive her parents from her.

To indicate a cause and effect relationship between actions that will take place in the future:

I will have been walking under the rain, till I be in home, because I forgot my umbrella.

Spelling variants of the future perfect continuous in English

Negative form. To express the negative form of the future perfect continuous in English, the negative particle, and in its case, the negative contraction, are applied in the auxiliary verb will; the structure have been + verb in gerund, they remain the same. In the case of going to, the negative is applied in the form of the verb to be:

We will not have been playing football - We won’t have been playing football

I shall not have been running until be tired - I shan’t have been running until be tired.

Raul is not goint to been traveling on July 22. - Raul isn’t going to be traveling on July 22.

Interrogative form. The interrogative form is made by prepending the auxiliary forms will or shall to the subject, which is followed by the structure have + been + verb in gerund remains the same. In the case of goin to, the interrogative phrase will begin with the verb form to be:

Will George have been reading the newspaper when Rose arrived?

Shall you have been training before the party?

Are we going to have been visiting the park for the weekend?

Exceptions

Not all actions can be expressed in the future perfect continuous. There are some verbs that only support the continuous form or the perfect form, but not combined:

1. Verbs that express emotions. When verbs express some emotions, they do not allow the use of the continuous perfect tense. Some of these verbs are for example believe (believe), love (love), wish (wish), think (believe). However, the same verb can have different meanings, and in certain contexts it admits the future perfect continuous.

2. Verbs that express the action of the senses. Hear, see, feel, smell, taste (hear, see, feel, smell, like) are verbs that also do not admit the future perfect continuous tense. There are some actions that are not action of the senses, but activities in which we use the senses. These actions do admit the future perfect continuous tense.

3. Verbs that express possession: own, belong, have, posses.

4. Verbs that express a state or way of being: to be (to be, to be), to seem, need (need), care (import), exist (exist).
