තුනෙන් එක, දෙගුණයකින්, ගෙඩියට: how Sinhala counts

A fraction is read from the bottom up: first the lower number with the tail -ෙන්, then the upper one. තුනෙන් එක is "one out of three", a third. දහයෙන් තුනක් is "three tenths". For example: “පඩියෙන් තුනෙන් එකක් කුලියට යනවා” — A third of the salary goes to rent. A rule from the Sinhala course: worked out on examples, not memorized as a wording.

How it works

A fraction is read from the bottom up: first the lower number with the tail -ෙන්, then the upper one. තුනෙන් එක (tunen eka) is "one out of three", a third. දහයෙන් තුනක් (dahayen tunak) is "three tenths".

Multiples take the tail -ගුණය: දෙගුණයක් (deguṇayak) is "twofold". For a rise or a fall -ෙන් is added: ගාණ දෙගුණයකින් වැඩි වුණා (gāṇa deguṇayakin væḍi vuṇā) — "the price doubled".

Pieces are counted with a counting word. Round things go through ගෙඩිය (geḍiya): පොල් ගෙඩි තුනක් ("three coconuts"), ගෙඩියට කීයද (geḍiyaṭa kīyada)? ("how much for one?"). People go through දෙනා: මිනිස්සු පස් දෙනෙක්.

"One and a half" is a single fused word, එකහමාර (ekahamāra), and the whole row follows that pattern: දෙකහමාර, තුනහමාර.

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.

“පඩියෙන් තුනෙන් එකක් කුලියට යනවා” (paḍiyen tunen ekak kuliyaṭa yanavā) — A third of the salary goes to rent. A rule is easier to test on sentences like this than to memorize as a wording: what surfaces in conversation is the sentence.
