Words like this, that, these, those are called "demonstratives." Papiamentu, unlike English, has a three-way system of demonstratives, corresponding to this, that, and "that one way over yonder."
The demonstrative adjectives consist of the multipurpose word e appearing before the noun, and aki or ei or aya appearing after the noun.
e pushi aki : this cat
e pushi ei : that cat
e pushi aya : that cat over there
Mi gusta e kas aki. I like this house.
E kas ei ta nobo. That house is new.
E kas aya ta grandi. That house over yonder is big.
The demonstrative pronouns are:
esaki : this
esei : that
esaya that one yonder
Esaki ta bon. This is good.
Mi no ta gusta esei. I don't like that.
Esaya ta su kas. That over yonder is his house.
It is possible to add the suffix -nan to create plural demonstrative pronouns such as esayanan (those over there). The following demonstrative pronouns also exist:
esun aki : this one
esun ei : that one
esun aya : that one way over there
