Pattern (morphological paradigm) name, optionally output by the morphological analyzer. It contains two parts, separated by a colon:
For example, if the dictionary pattern name is s2, and the actual ending pattern is y, the markup is <pn>s2:y.
The source dictionary pattern name (s2 in the above example) is the one which is manually inserted to the source main dictionary when adding a new word (dictionary entry). However, this pattern in general does not correspond directly to the actual ending database pattern name, since it is first processed by the [regular] derivation module (which is part of the morphological processor), and replaced by another "virtual" entry (or even expanded to a set of virtual dictionary entries), with possibly different root and lemma, which then uses a matching pattern name from the set of patterns from the ending database. This whole process is done on-the-fly and does not entail any special preprocessing steps other than regular dictionary compilation for the morphological analyzer.
The pattern name(s) have no importance for further linguistic processing, but they might be interesting for other reasons. No set of pattern names is generally provided with the data and this description (as opposed to, e.g., the morphological tags), but it might be made available on request.
