Udenian is a logical, isolating conlang, that does away with the ambiguity and unnecessary grammatical rules that the rest of the world's languages tend to burden their speakers with. Once you have learnt how the language works, there are clear, understandable, and consistent rules for how to form the correct grammar, and that is the logical aspect of Udenian.
Provided you know how to read Cyrillic script, learning Udenian as an English speaker should be reasonably easy, as it uses a lot of similar grammar rules, such as: a "subject > verb > object" sentence structure, a gender-free noun lexicon, a system where adjectives come before nouns (and adverbs after verbs), a progressive tense which is made in a similar way etc... the only immediately noticeable differences would be; which conjugations of verbs are for which subject type, and how those conjugations work; how one goes about making an expression negative (eg. I do not like eggs); and how you form plurals of nouns.
Plurals of nouns are formed by adding the word 'е' in front of them. Eg. translator = трансязъсредсска, translators = е трансязъсредсска
Sometimes translation isn't as accurate as you might like it to be, so here's some help with verb conjugations:
All verbs end in 'т', but not all words that end in 'т' are verbs. The following 'modifier' words are added after the infinitive form of the verb to form the conjugated form:
First person sing. = ирт
First person pl. = ерт
Second person sing. = ихт
Second person pl. = ехт
Third person sing. = ист
Present Progressive Tense:
Verbs do not conjugate regarding subject or object type in the present progressive tense. The word 'вре' follows the infinitive form of the verb.
You do not need to use the verb 'be' in conjunction with present progressive verbs, for instance, the literal translation of 'я нэ вооят ирт правят һуут' (I am not going to do that) is 'I not will do that'.
Past Progressive Tense
To form the past progressive of a verb, insert the word 'врез' after the infinitive of a verb. Verbs do not conjugate regarding subject or object type in the past progressive tense.
The past tense form of 'be' is not needed with the past progressive tense, eg. "where were you going?" becomes "ваар вы гэгаат врэз?", which literally means "where you 'going-ed'?"
Add 'з' after the word to form the past tense.
The past participles of verbs are formed the same way as explained above. 'Ымят' ('have') may be used with past-tense verbs to emphasise additional implications/connotations, but its presence is not necessary.
Example: "Where have they gone?" translates to "ваар гэгаат з етов?", which literally means "where gone they?", but one can also say "ваар ымят ест етов гэгаат з?", meaning "where have they gone?", but that would be said in the context of someone being puzzled as to someone's whereabouts, so extra emphasis would be put on the word 'ымят'.
The Future Tense
In Udenian, you cannot say that you are 'going to' do something when forming the future tense, unless you are actually going somewhere, in order that you might enact a verb. Instead, you use the more literal auxilary verbs: 'вэрдат' (shall) and 'вооят' (will). Here's an example of a sentence in the future tense: "Ёв вооят ерт гэгаат в ан һодына," which means "we are going to eat in an hour," but the literal translation is "we will eat in an hour."
To form the imperative form of a verb (when you tell someone to do something, eg. 'go away'), insert the word 'вор' before the verb.
Pronunciation of some Prepositions
When a single-letter preposition, such as 'к' (to) or 'в' (in), follows/precedes a word that ends in/begins with a vowel, you should pronounce it almost as if the preposition is part of the target word, unless it makes it sound like another word, in which case, you should say the preposition as if it had a 'ъ' mark following it. If the preposition is surrounded by a vowel on either side, you should try to 'move' the sound of the preposition closer to the word that follows it. Examples:
'к ан короштийа плаацэ' (to a nice place) is pronounced 'к-ан короштийа плаацэ'
'вы бордя з, айнз...' (you should, like...) is pronounced 'вы бордя-з, айнз', not 'вы бордя, з-айнз', because there is a comma between 'з' and 'айнз'.
'в ан виазният' (in a hurry) is not pronounced as 'в-ан виазният', but as 'въ ан виазният', because it would sound like you are saying 'ван виазният', meaning 'of hurry'.
The Order of Verb Modifiers
When you need to add a lot of extra modifiers around a verb, it can be difficult to know what order to put them in, so here's some help:
You'll never need to add multiple modifiers after a verb
'жна' (the formality indicator) always comes before all the other modifiers, because it shows that the whole verb and the additional information it carries is being said formally
'вор' (the imperative mood indicator) goes at the very front, unless 'жна' is being used, as is often the case with 'вор', and in that case, it comes straight after the former.
