Please allow me to quote the two sections concerning these types of formations from Atanquesta:
Verbs: Impersonal
Whenever an English sentence contains a predicate (which usually contains a verb or copula), it will have a subject (sometimes only implied, as in imperative sentences like Come!). There are situations though where this subject is a very generic one, usually the pronoun it, like in these examples: It’s raining again. It seems to me that we are in agreement.
In Atanquesta the language deals with this sort of situations by allowing certain verbs to appear in a subjectless, so called impersonal conjugation. This means that the verb has no subjects, either standalone or as a pronominal suffix, so it will appear in the sentence in its bare tense form without pronominal suffixes; if the verb has a beneficiary/recipient, it will be in dative case. Here are some examples:
kelya- “to rain” Kelya. “It rains; it’s raining.”
niku- “to be cold, to freeze” Nique. “It is cold. It freezes.”
nem- “seem, appear” Neme nin raumo túla. “It seems to me [that] a storm is coming.”
óla- “dream” ólane sen sa wilwarin nése. “He dreamt [lit. it dreamt to him] that he was a butterfly.”
mauya- “compel, oppress” Mauya men tuve analta lunte. “We must [lit. it compels us to] find a bigger boat.”
or- “to warn, urge, feel an urge/wish/desire” This is a special one as this verb has two possible aorist forms with slightly different meanings, ora and ore. Ora nin lasselanta nauva vanima si loas. “Something tells me/I have a feeling [lit. it warns me] that autumn will be beautiful this year.” Ore nin kape alassenen. “I would like to/it feels like/I need to leap with joy.”
ek- “may, have a chance or opportunity”; eke men tyale enar? “can we/may we play tomorrow?” Neme nin Anar kaluva enar; ekuva tyen moia i lotarwasse. “Looks like the sun will shine tomorrow; you will have a chance to work in the garden.”
Verbs: Auxiliary Phrases: May, Can, Know, Must etc.
Just like English, Atanquesta has a number of verbs that are used as auxiliaries, i.e. verbs that are coupled with infinitives to express intent, chance, possibility, need etc. Think of I must eat, you can dance, I dare not go, etc. We have the following in Atanquesta:
ek-, or-, and mauya- were discussed in the previous section Verbs:Impersonal
pol- “can, be able to (physically)” polin teke “I can write” (because I am healthy and nothing physical prevents me)
ista- “can, know (how to)” istan teke “I can write” (I know how to write because I have learnt it)
lerta- “can, be free to, be allowed to” lertan teke “I can write” (I am free to do it, no one has permitted or prevented me)
mer- “want, wish, hope” merin teke “I want to write, I wish to write”
If you want to follow the verb with an object pronominal suffix, you’ll need to use the particular infinitive: lertan tekitas “I can write it”, merin hentaitat “I want to read them”.
