Verb Tenses
Today we’re going to be talking about the difference between present perfect, past perfect, and future perfect verb tenses.
Remember that verbs are words that describe an action, occurrence, or state of being. The tense of a verb refers to the time of the action or state of being. The perfect form is the verb tense used to talk about a completed action or condition and always uses a form of “have” or “had,” plus the past participle.
Participles are words made out of verbs but used as adjectives. In English, participles are also sometimes used to form compound words like “is going.” A past participle, in the context we’re using it today, is the second part of a compound verb that’s used to form perfect and passive tenses. Past participles usually end in -ed.
Verbs can appear in any one of three perfect tenses: present perfect, past perfect, and future perfect.
Present Perfect
Let’s start by talking about present perfect verbs. The present perfect tense expresses an action that began in the past and is now completed in the present. Take a look at this equation:
Present Perfect Tense Example
We can put those elements into practice in the following sentence.
We know this sentence is written in the perfect tense for two reasons. First, we see that it is talking about a completed action: “I have finished my homework.” There’s our -ed past participle, and it’s telling us that the job is completed. The second hint we have that it’s the perfect tense is the word have. Remember, the perfect form is a verb tense that uses a form of have or had plus a past participle.
In this sentence, have finished tells us that the finishing action began in the past but is now completed in the present. We can see that the sentence used have instead of had, so we know it’s present perfect tense, not past perfect.
Past Perfect
The past perfect tense expresses an action that began in the past and was completed in the past before something else occurred. The past perfect equation looks like this:
Past Perfect Example
Here’s a sentence with past perfect tense.
Right away, our eyes should be drawn to the past perfect phrase had broken. There’s our past tense had and our past participle. You may notice that broken is not an -ed verb, but it’s still a past participle; it just conjugates differently than the -ed verbs we’ve looked at so far. This also happens with words like ate and shaken. The sentence is describing something that began in the past and was completed before something else occurred. Paul broke the vase. The action is complete, therefore the tense is perfect, and it happened in the past, therefore the word had appears in our equation.
Future Perfect
The future perfect tense expresses an action that will be completed by some specified point in the future. This equation is a little more exciting.
Future Perfect Tense Example
Here’s a sentence with future perfect tense.
First, we notice the two elements we’ve learned to expect from the perfect tense: a version of have or had, and a past participle, in this case, the -ed verb cooked. You might be tempted to think this was present perfect tense based on our earlier equation, but be careful to look first in front of the word have to make sure it’s not future perfect. Sure enough, the entirety of the phrase reads will have cooked.
This tells us that we’re talking about an action that’s not done yet, but will be done in the future at a specific time. Take, for example, the following phrases:
In two years, I will have saved $2,000.
In both these examples, the reader is standing in the present without evidence of a completed action, but we can be sure that both of those things will be done in the future, thus the past participles danced and saved.
It may sound complicated, but if you remember these three grammar equations and acquaint yourself with common past participles, you’ll have a solid understanding of present perfect, past perfect, and future perfect tenses.
I hope this overview was helpful!
