Ilocano has two number systems: one is native and the other is derived from Spanish. The systems are virtually used interchangeably. Yet, the situation can dictate which system is preferred.
Typically, Ilocanos use native numbers for one through 10, and Spanish numbers for amounts of 10 and higher.
Specific time is told using the Spanish system and numbers for hours and minutes, for example, Alas dos/A las dos (2 o'clock).
For dates, cardinal Spanish numbers are the norm; for example, 12 (dose) ti Julio/Hulio (the twelfth of July).
As with other roots in the language, numbers can undergo various forms of agglutination.
Cardinal numbers are those used in counting.
