Word building

It's possible to build new words in Pandunia. Pandunia has a productive system of word derivation. Most of the suffixes that are used in Pandunia are already in international use. Many of them come from ancient Greek, Latin, Arabic and Persian.

Word class markers

Pandunia uses vowel endings for quick word derivation. In this system the final vowel of a word indicates its word class. So the root (i.e. stem) of the word indicates a general idea and the vowel endings indicate different manifestations of that idea.

Pandunia uses the following vowel endings to mark parts of speech.

  • no vowel or -e indicates a noun (a thing)
  • -i indicates an adjective (a description)
  • -o indicates an adverb (a manner or a circumstance)
  • -a indicates an active verb (an action)
  • -u indicates a passive verb (an event)

They are the only true suffixes i.e. bound morphemes in Pandunia. All other suffixes can be used also as independent words. For example paciste (pacifist) is made up of two full words: pace (peace) and iste (proponent).

The designated vowel endings enable easy derivation of one type of word from another. An ending is simply changed to another ending.

  • The ending -e converts the idea into a thing. For example nile means the color blue.
  • The ending -i converts the idea into a description. The resulting modifier describes another idea with the modifying idea. For example nili dome means a blue house.
  • The ending -a converts the idea into an action. The resulting verb is about applying the idea to an object. For example nila dome means "to make the house blue".
  • The ending -u creates an action just like -a. The only difference is that the word order is reversed so that the object comes first. For example dome nilu means "the house becomes blue".

All endings can be applied on all ideas in the same way.

Here are a few examples of different types of ideas.

  • concrete action
    • kitabe a writing (noun)
    • kitabi written, textual (adjective)
    • kitabo by writing
    • kitaba to write (active verb)
    • kitabu to be written (passive verb)
  • abstract action
    • fikre a thought (noun)
    • fikri thinking (adjective)
    • fikro by thinking (adverb)
    • fikra to think (active verb)
    • fikru to be thought (passive verb)
  • description
    • longe length (noun)
    • longi long, lengthy (adjective)
    • longo lengthily (adverb)
    • longa to make long, to lengthen (active verb)
    • longu to get long, to be lengthened (passive verb)
  • tool
    • hamar a hammer (noun)
    • hamari "hammery", hammerlike (adjective)
    • hamaro by/with/like a hammer
    • hamara to hammer, to apply hammer on sth (active verb)
    • hamaru to be hammered (passive verb)

Deriving verbs

-a and -u are the endings for verbs.

  1. If the stem's idea is an action, then its verb form will mean "to do the action". For example from vide (a look) we get vida (to look).
  2. If the idea is a description then its verb form will mean "to turn into that quality". For example from novi (new) we get nova (to make new or to renew).
  3. If the idea is a thing, then its verb form will mean "to apply it to". For example from hamar (hammer) we get hamara (to hammer).

Deriving nouns

-e is the ending for nouns.

If the stem's idea is an action, then its noun form will mean the result or the product of the action. For example from kitaba (to write) we get kitabe (writing or text).

If the idea is a description, then its noun form will mean a concrete instance of that quality. For example from novi (new) we get nove (a novelty i.e. something new).

Additional noun suffixes are presented below.

Deriving adjectives

-i is the ending for adjectives and adjectival verbs.

If the stem's idea is a description, then its adjectival form will mean "that which is in the state of the root". For example from nov- (newness), we get novi (new i.e. that which is new).

If the idea is an action, then its adjectival form will mean the state that is produced by the action. For example from loga (to speak) we get logi (spoken).

If the idea is a thing, an object or a person, then its adjectival form will mean "that which is like the root". For example, from the noun insan (human being), we get the adjective insani (human, having the attributes of a human being).

If the root is a place word, then its adjectival form will mean "that which is from that place".

Irania Iran, Irani Iranian
Pakistan Pakistan, Pakistani Pakistani
Amerike America, Ameriki American
Europe Europe, Europi European
Asia Asia, Asi Asian

Words without a vowel ending

Normally, when a word doesn't end in a vowel, it is a noun. The noun ending -e is used only when the word would be otherwise difficult to pronounce by international speakers. So it is necessary to use -e after stop consonants (ex. supe instead of sup), affricates (ex. noche and laje instead of noch and laj), voiced fricatives (ex. nove and taze instead of nov and taz) and consonant series (ex. poste and yogurte instead of post and yogurt). Otherwise nouns don't have a vowel ending.

In addition, a handful of adjectives and adverbs don't have a vowel ending. The adjectives without the ending are bon (good), mal (bad), lil (small) and day (big). The advebs withouth the ending are mas (more) and min (less).

Note that it is always acceptable to use the vowel endings on every word. So it is acceptable to say boni hotele instead of bon hotel (a good hotel).

Compound words

Two or more roots can be put together to make a compound word. The last root is the most meaningful part in the compound and the roots that come before it only modify its meaning.

Compound words are made of bare word stems and a vowel ending.

For example, this is how the word andewisti (atheistic) is made:

       an       (negation)
   +  dew       (god)
   +  ist       (proponent, -ist)
   +    i       (adjective ending)

= andewisti (atheistic)

If joining bare stems together would result into a difficult consonant sequence, a padding vowel -o- is inserted between them.

For example, this is how termometer (thermometer) is made:

     term       (temperature)
   +    o       (padding vowel)
   +  met       (measuring)
   +   er       (device)
= termometer    (thermometer)

Function Words

Function words are words that help to organize words into more or less complex sentences. It is a closed class i.e. new words are never or only very seldom be added to it. Function words behave by definition differently than content words, which is the open class for words that refer to things in the world outside the structure of the language.

In Pandunia, function words have the following characteristics:

  1. The word is made up of one consonant and one vowel.
  2. The consonant indicates the general idea of the word.
  3. The vowel has a structural meaning, as follows:
    • -e indicates a pronoun
    • -i indicates a determiner or a modifier
    • -o indicates an adverb
    • -a indicates a preposition
    • -u indicates a postposition
