One and many: number for the rational and the irrational

The division into rational and irrational is familiar from wave 1: people on one side, things and animals on the other. For the plural this division is drawn even sharper, and the rule is simpler than it seems. For example: “ரெண்டு பேர் வந்தாங்க” — Two people came. A rule from the Tamil course: worked out on examples, not memorized as a wording.

How it works

The division into rational and irrational is familiar from wave 1: people on one side, things and animals on the other. For the plural this division is drawn even sharper, and the rule is simpler than it seems.

For the rational the plural is obligatory and stands where it should: -கள் on the noun and -ஆங்க on the verb. பிள்ளைகள் பாடசாலைக்கு போறாங்க (piḷḷaigaḷ pāḍasālaikku pōṟāṅga) — 'the children go to school'. People are counted with the counter word பேர் (pēr): ரெண்டு பேர் (reṇḍu pēr) 'two people', எத்தனை பேர் (ettaṉai pēr)? 'how many people?'. Politeness fits in here too: about one respected person one says the plural அவங்க (avaṅga), and the verb also goes to -ஆங்க.

For the irrational it is the reverse: with a numeral no plural is used at all. ரெண்டு பெட்டி இருக்கு (reṇḍu peṭṭi irukku) — 'there are two suitcases', without -கள் and with the verb in the singular. Saying ரெண்டு பெட்டிகள் இருக்குங்க is impossible: the numeral has already reported the quantity, and the language considers repeating it with an ending superfluous. The same with நிறைய (niṟaiya) 'many': நிறைய கொசு இருக்கு (niṟaiya kosu irukku).

The ending -கள் does happen with things — where objects are thought of separately and without counting: பொருட்கள் (poruṭkaḷ) 'things', `வாழ்த்துக்கள் (vāḻttukkaḷ)' 'wishes'. The rule does not break because of this: the ban concerns exactly the combination 'numeral + thing'.

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.

Frequently asked

One and many: how does it work in Tamil?

The division into rational and irrational is familiar from wave 1: people on one side, things and animals on the other. For the plural this division is drawn even sharper, and the rule is simpler than it seems.

What does it look like in an example sentence Tamil?

“ரெண்டு பேர் வந்தாங்க” (reṇḍu pēr vandāṅga) — Two people came. A rule is easier to test on sentences like this than to memorize as a wording: what surfaces in conversation is the sentence.
