Ordinal Numbers and Something

Forming ordinals is way too easy. Just pick the number you want and add -tte for the ones ending in a vowel and -te if it ends with -n. It does apply to every number except bir "one" and ni "two", that becomes riszon "first" and szeni "second", respectively.

• sa → satte (3rd)
• ho → hotte (4th)
• go → gotte (5th)
• so → sotte (6th)
• ste → stette (7th)
• ka → katte (8th)
• ku → kutte (9th)
• ju → jutte (10th)
• niju → nijutte (20th)
• saju → sajutte (30th)
• han → hante (100th)
• sen → sente (1000th)
• miliona → milionatte (1000000th)

For compound numbers, the rule is same:

• ju-sa (13) → ju-satte (13th)
• niju-sa (23) → niju-satte (23rd)
• hosen-goju (450) → hosen-gojutte (450th)
• usen-kuhan-kuju-ku (1999th) → usen-kuhan-kuju-kutte (1999th)
• nisen-ju-go (2015)  → nisen-ju-gotte (2015th)

Some expressions on numbers:

• Mai gotte iv → every fifth year. The word mai is used within time expressions only.
• Mitriszon elsatte iv → since the first until the third year. Note the prefixes mit- "from" and el- "to" attached just onto the numbers because they are acting as noun extensions in relation with the noun iv "year", avoiding its necessity of being repeated.
