Rational and irrational
The main division of Tamil grammar runs where an English speaker never looks for it. Gender has nothing to do with it: the language divides everything into rational (உயர்திணை) and irrational (அஃறிணை). The rational — people and gods. The irrational — everything else: things, plants, weather and, most surprising of all, animals. To Tamil grammar a dog is as much of an object as a table. For example: “டாக்டர்…
How it works
The main division of Tamil grammar runs where an English speaker never looks for it. Gender has nothing to do with it: the language divides everything into rational (உயர்திணை) and irrational (அஃறிணை). The rational — people and gods. The irrational — everything else: things, plants, weather and, most surprising of all, animals. To Tamil grammar a dog is as much of an object as a table.
This division rules three things at once. The first is the verb: with a rational subject it ends in -ஆர்/-ஆங்க, with an irrational one in -உது/-இருக்கு (-irukku). 'The doctor is here' — டாக்டர் இங்கே இருக்கார் (ḍākṭar iṅgē irukkār); 'the table is here' — மேசை இங்கே இருக்கு (mēsai iṅgē irukku).
The second is the pronoun: about a person one says அவர் (avar), about a thing அது (adu). The third is the plural: for the irrational it is simply not used with a numeral. ரெண்டு நாற்காலி இருக்கு (reṇḍu nāṟkāli irukku) — 'there are two chairs are', with no -கள் at all and the verb in the singular.
The practical conclusion is short: hearing -உது at the end of the verb, look for a thing, not a person, as the subject. And the reverse — saying இருக்கு (irukku) about a person instead of இருக்கார் (irukkār) sounds not just uneducated but rude.
Table
| Who/what | There is, is present | Pronoun |
|---|---|---|
| டாக்டர் (a person) | இருக்கார் | அவர் |
| ஆசிரியர் (people, pl.) | இருக்காங்க | அவங்க |
| மேசை (a thing) | இருக்கு | அது |
| நாய் (an animal) | இருக்கு | அது |
By example
- டாக்டர் அலுவலகத்தில இருக்கார்ḍākṭar aluvalagattila irukkārThe doctor is in the office
- மேசையில சாவி இருக்குmēsaiyila sāvi irukkuThe key is on the table
- ரெண்டு நாற்காலி இருக்குreṇḍu nāṟkāli irukkuThere are two chairs
How the rule settles in your head
A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
