Besesk uses the Latin alphabet:
A B C Č D E F G H I J K L M N O P R S Š T U V Z Ž
The letters Q, W, X and Y are not used natively.

Pronunciation: All letters are pronunced in the same way as the IPA phonemes.

Penultimate Stress Rule: Primary stress always falls on the second-to-last syllable

Nouns have no grammatical gender. There are also no cases. The basic noun remains unchanged. However, speakers can optionally use non-obligatory genders and cases.

Plural
Add +i.
* dom → domi

Consonant clusters: allowed but epenthetic vowel +o may be inserted, especially for compounds.

Besesk uses simple articles.

Definite
la = the
la dom = the house

Indefinite
jeden = a/an
jeden dom = a house

Adjectives don't change for gender or number. However, speakers can optionally use declensions.
Most adjectives end in +ni.

la grandni dom
=the big house

Most adverbs end in +no.

The adjective comes before the noun.
The adverb also preferably comes before the verb or adjective.

Optionally, +eni and +eno is used for clusters.

Io es studnik.
I am a student.

However, speakers optionally can use pronouns with the accusative case.

The possessive precedes the noun:
muj dom - my house

Possessive adjectives: +uv

Every infinitive ends in +ar.
mluvar - to speak

Io mluvu Besesk.
I speak Besesk.

Past tense: Use ha + active participle
Active participles end in +l.
mluvar > mluval

Io ha mluval.
I spoke / I have spoken.

Future tense: va + infinitive

Io va mluvar.
I will speak.

esar = am/is/are
However, the shortened es can also be used for any conjugation.

Passive voice: Use es + passive participle
Passive participles end in +t.

Imperative mood: +te
Optionally, +ejte is used for clusters.

Simply put ne before the verb.

Io ne mluvu Besesk.
I don't speak Besesk.

Questions don't require inversion. Add že to form a question.

Tu mluvaš Besesk.
You speak Besesk.

Tu mluvaš Besesk že?
Do you speak Besesk?

Question words are usually at the beginning, while že is usually at the end.

Kde tu aložaš?
Where do you live?

Besesk uses simple prepositions rather than case endings. However, users can optionally use the accusative case after prepositions.

Io aložu v Praha.
I live in Prague.

La isol fisa.
Io sedu e pišu la dnesuv napiš pod la baldakien di šuotal dlanalber. Tak delikatni ilusion. Behem la dlan šuotar, io ne mocu ne mieslar, ke li oserva me e prejedna do moje naladi. Nejak tento isol viva. Li viva podle cest pri jenž mie človekni aložniki ankora ne košientano, e li oserva. Li oserva forse s sensorgani en la pianti, forse podle cesti jenž io ne mocu imažinar. Kdiebie io mocu jak tento luog vivar, li esa la imažin di sen nebo fiab zkazar. Io prece sapu to... behem tento sen kontinar, ši riekleno diventa inkub. E ankora la isol fisa e atenda.

Translation:

The island watches.
I sit and write today's entry under the canopy of a swaying palm tree. What a tender illusion. As the palm sways, I can't help but think it is observing me and reacting to my moods. Somehow this island lives. It lives in a way we human inhabitants are not yet aware of, and it watches. It watches, perhaps through sensory organs in the plants, perhaps in ways I can't imagine. If I could imagine how this place lives, it would be the imaginings of a dream or a fairy tale gone awry. I do know this--as this dream continues, it is quickly becoming a nightmare. And still the island watches and waits.
