|  | In the UNLarium framework, the distribution must be informed through [[s-rule]]s, except in case of exceptional (non-default) cases, to be registered in the dictionary by the following values:
 |  | 
|  |   |  | 
|  | {{#tree:id=DIS|openlevels=0|root=Distribution (DIS)|
 |  | 
|  | *order (PSN)
 |  | 
|  | **front(FRT): at the beginning of the clause
 |  | 
|  | **premodifier (BEF): coming before the modified 
 |  | 
|  | **postmodifier (AFT): coming after the modified
 |  | 
|  | **middle position (MID): coming in the middle of the modified
 |  | 
|  | **end (END): at the end of the clause
 |  | 
|  | **free (FRE): coming in any position
 |  | 
|  | *adjacency (PXM)
 |  | 
|  | **immediate (IMM): right after or right before
 |  | 
|  | **near (NEA): precedence over other constituents (except IMM)
 |  | 
|  | **distant (FAR): no precedence over other constituents

|  | === Examples ===
 |  | 
|  | *Order
 |  | 
|  | **very = BEF - In English, the intensifier "very" is a premodifier: ''He is very rich'' (<strike>''He is rich very''</strike>)
 |  | 
|  | **well = AFT - In English, the adverb of manner "well" is a postmodifier: ''He speaks well'' (<strike>''He well speaks''</strike>)
 |  | 
|  | **yesterday = FRE - In English, the adverb of time "yesterday" may come either before or after the modified: ''Now I go'' or ''I go now''.
 |  | 
|  | *Adjacency
 |  | 
|  | **the = FAR (In English, the article "the" has no precedence over other modifiers: ''the small round black leather handbag'' (<strike>small the round black leather handbag</strike>).
 |  | 
|  | **after (in "look after") = IMM (In English, the preposition after must come right after the base form "come" in order to form the compound "look after": ''We look after them'' (<strike>We look them after</strike>)

|  | === Observations ===
 |  | 
|  | ;The distribution of words must be informed in the dictionary only if variable.
 |  | 
|  | :The field "distribution" must be filled in only if different words of the same category may occur in different positions
 |  | 
|  | ::Adverbs, in English, may be premodifiers or postmodifiers. Therefore, distribution of adverbs must be informed in the dictionary.
 |  | 
|  | ::Articles, in English, are always premodifiers. Therefore, distribution of articles must not be informed in the dictionary.
 |  | 
|  | ;The distribution of words must be informed in the dictionary only if not the default one.
 |  | 
|  | :The grammar brings the normal (default) distribution of the words in a language. Only exceptions to the rule must be informed in the dictionary.
 |  | 
|  | ::Adjectives, in English, are normally premodifiers. Therefore, distribution of premodifier adjectives (such as "beautiful") must not be informed in the dictionary. On the other hand, free order adjectives (such as "possible": "it is the only solution possible" or "it is the only possible solution") must be tagged, in the dictionary, with the corresponding feature (FRE).
 |  | 
|  | ;Middle position should be used only for words to be inserted inside others (i.e., between the prefix and the root, or the root and the suffix).
 |  | 
|  | ::Adverbs coming between auxiliaries and verbs must be defined as premodifiers.
 |  | 
|  | ;Distribution values are not exclusive:
 |  | 
|  | :BEF&AFT means that the word may occur both as a premodifier or as postmodifier;
 |  | 
|  | :BEF&MID means that the word may occur both as a premodifier or as a middle modifier.
 |  | 
|  | ;Order and adjacency may be combined to express specific distributions:
 |  | 
|  | :BEF&IMM means that the word occurs right before the modified (as with English intensifiers)
 |  | 
|  | ;Order must be informed only when required:
 |  | 
|  | ::English intensifiers must come right before the intensified ("very well"), therefore BEF&IMM;
 |  | 
|  | ::Adverbs of manner normally comes after the complements ("She read the letter slowly"), therefore "AFT&FAR";
