Expressions own preset modes or region or social group. For example: -Quiubo -Oi -Aja
That's, There, ¡ay!
Something similar happens with these 3 ways, very repeated in colloquial and formal Spanish, so we must identify them. - That's an adverb of place, so it is the same: it is always written with "h" sandwiched. - There is a conjugated form of the verb "to have".
- Ay! It is an expressive interjection is usually between exclamations (though not required) and is written without "h" and "and" in all instances.
Thank you for your attention!
