Rational and irrational
The main split in Tamil grammar is not where you would look for it. Gender plays no part. The language sorts everything into rational — people and gods — and irrational — all the rest. Things, plants, weather, even animals: a dog here is as much an object as a table. For example: “டாக்டர் அலுவலகத்தில இருக்கார்” — The doctor is in the office.

How it works
The main split in Tamil grammar is not where you would look for it. Gender plays no part. The language sorts everything into rational — people and gods — and irrational — all the rest. Things, plants, weather, even animals: a dog here is as much an object as a table.
The split rules three things. The verb first: with a rational doer it ends in -ஆர் or -ஆங்க, with an irrational one in -உது. டாக்டர் இங்கே இருக்கார் (ḍākṭar iṅgē irukkār), மேசை இங்கே இருக்கு (mēsai iṅgē irukku).
The pronoun second: about a person அவர் (avar), about a thing அது (adu). The plural third: after a numeral a thing drops it. ரெண்டு நாற்காலி இருக்கு (reṇḍu nāṟkāli irukku) — two chairs, no -கள், verb in the singular.
So when -உது closes the verb, look for a thing as the doer. And இருக்கு (irukku) about a person sounds not merely wrong but rude.
Table

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.
