The perfect tenses include:
- Present Perfect ("I have chosen")
- Past Perfect ("I had chosen")
- Future Perfect ("I will have chosen")
Think of them as the "complete tenses" as they describe a finished activity.
The perfect tenses are formed using the perfect aspect.
The perfect aspect is the combination of conjugated auxiliary verb "to have" and active verb's past participle. The verb to have detemines whether a sentence has a present (have/has seen), past (had seen) or future (will have seen) meaning.
Continuous + perfect
If we combine the continuous and perfect tenses, we get:
- Present Perfect Continuous ("I have been choosing")
- Past Perfect Continuous ("I had been choosing")
- Future Perfect Continuous ("I will have been choosing")
