Perfective and the aspectual verb இரு

The perfective in Tamil is expressed using இரு. இரு as an aspectual verb, like all other aspectual verbs, is added after AVP form of a verb with the meaning that the action has happened but still continues, or is relevant to the discussion at hand. When in the future or in the conditional, it is usually translated as 'would have VERB' (the "pluperfect") Rather than add a glide, if the AVP ends in a vowel, the final vowel is dropped. Negation of the perfect happens in a number of different ways, depending on the tense of இரு, the AVP (experiential or not), and whether the action/event denoted is habitual or not.

Imminent action

Perfective tense is used to denote any event that has already occurred but is current/relevant at the time of utterance.

1. இன்றைக்கு என்னுடைய அப்பா என்னுடைய அறைக்கு வந்திருக்கிறார் 'My father has visited me in my room (in the dormitory).

2. நான் நிறைய சப்பிட்டிருக்கிறேன். என்னால் இப்பொழுது உங்களோடு ஹோட்டலுக்கு வரமுடியாது. 'I have eaten too much. I can't come to the restaurant with you now.

3. நிறைய தண்ணி போட்டிருக்கிறார். நடக்கவே முடியவில்லை. 'He is drunk. He is unable to walk.

Past PerfectWhen இரு is in the past tense, the action is relevant to some point in time before the time of utterance (i.e., it already happened/was relevant with respect to a particular time in the past).

4. நான் நேற்று ஐந்து மணிக்கு அவருடைய வீட்டுக்குப் போனேன். அப்போது அவர் கடைக்குப் போயிருந்தார். 'At the time when I went to you his house, he had been to a store.'

When used in combination with conditional and/or the future, this suffix expresses the 'plu perfect' meaning (also called doubtful past), which means that the action didn't really happen, but there was chance for it to take place. Note that the second sentence is also an AVP plus இரு in the future tense.

3. எனக்கு தெரிந்திருந்திருந்தால், நான் வந்திருப்பேன். 'If I knew, I would have come.'

4. நீங்கள் அந்த வீட்டுக்குள்ளே போயிருந்தால் நாய் உங்களை கடித்திருக்கும். If you had gone inside that house, the dog would have bitten you.

5. இந்நேரம் என்னுடைய தம்பி இந்தியாவிலிருந்து நியூயார்க்குக்கு வந்திருப்பான்.
My younger brother would have returned to New York from India (might be in New York) by now.

6. நீங்கள் மட்டும் நேற்று என்னுடைய வீட்டுக்கு வராமல் இருந்திருந்தால் நான் ஒரு நல்ல தமிழ் சினிமாவுக்குப் போயிருப்பேன்.
If you hadn't come to my house yesterday, I would have gone to a good Tamil movie yesterday.

Future perfect in future time

7. அடுத்த மாதம் இந்நேரம் நான் இந்தியாவுக்குப் போயிருப்பேன்.
By this time next month I will have gone to India.

8. நான் நாளைக்கு உங்கள் வீட்டுக்கு வந்திருப்பேன் என்று வேண்டுமென்றே உன்னுடைய மாமியார் இன்றைக்கு வெளியூருக்குக் கிளம்பிவிட்டார் பாருங்கள்.
Having already known that I will have come to your house, your mother-in-law had left for another town today.

9. நாளைக்குக் காலையில் எட்டு மணிக்கெல்லாம் எல்லோரும் அலுவலகத்துக்குப் (office) போயிருப்பார்கள், நாம் நிம்மதியாக எட்டரை மணியிலிருந்து சினிமா பார்க்கலாம்
Everyone will have gone to their office by eight o'clock tomorrow, so that we can see the Tamil movie from eight thirt onwards peacefully.

Future Perfect Negation

10. நீங்கள் இப்படி தொண தொணவென்று பேசுவீர்கள் என்று தெரிந்திருந்தால் னான் உங்களோடு சினிமாவுக்கு வந்திருக்கவேமாட்டேன்.
If I had already known that you would blabber like this, I wouldn't have come with you to the movie.

11. இன்றைக்கு எட்டு மணிக்கெல்லாம் தூங்கியிருக்கமாட்டேன், னீங்கள் என்னைப் பார்க்க வரலாம்.
You can come and see me at eight o'clock, I will not have slept by then.

Experience

Unlike the imminent, past and future perfect denoting actions/events, இரு can also be used to express someone's experience of having done something in the past. Even though the forms that give this meaning is very similar to the present perfect forms, the meaning of habituality can be understood only through the context. The difference between these uses of the perfect is evident in its negation. The negation of the perfect when used to describe an experience takes a different form than the present perfect.

1. அவர் சிக்காகோவுக்கு போயிருக்கிறார். 'He has been to Chicago.'

This sentence tells that 'he' went to Chicago at some point in the past. It could be just past month, a year or many years before.

Habitual negation and the negation of இரு to denote an experience Habitual negation is made by adding இல்லை to a nominal form of the main verb. This structure is also used to negate the perfect when used to describe some experience. Structure: AVP-இரு-tense-அது-இல்லை. The tense can be in the past, present, or future. When in the past tense, it negates the experience of some action.
நான் தாஜ்மஹாலைப் பார்த்ததில்லை. I have not seen the Taj Mahal.

அவர் அவர்களுடைய குரலைக் கேட்டதில்லை. He has not heard her voice.

நானும் உங்கள் வீட்டில் சாப்பிட்டதில்லை. I also haven't eated at your house.

Alternatively, one can also put the main verb in the negative AVP form:
அவர்கள் படிக்காமல் இருக்கிறார்கள். 'They have not been reading.'

When இரு is in the present or future tense, the negation is of habitual action. In spoken Tamil, the future of இரு in aspectual negation is not used. கவலை படாதீர்கள். நான் எதுவும் மறக்கிறதில்லை/மறப்பதில்லை
Don't worry. I don't usually forget anything.
