Overview

CompoundForm is a hypothesis of how some word could be split into several AffixForms (word parts with their own stems and possible affixes).

Typically, only first part is allowed to have prefix, and only last part is allowed to have suffix, but there are languages where middle parts can have affixes too, specified by special flags.

  @parts = parts

end

Instance Attribute Details

#junction_patterns ⇒ Array<Readers::CompoundPattern, nil> (readonly)

Junctions sit between parts, so a compound of N parts has N-1 of them. The list is built front-to-back exactly like parts and holds the CHECKCOMPOUNDPATTERN whose replacement rebuilt each junction, or nil where the parts simply met. A shorter list means the trailing junctions are ordinary.

Returns:

def junction_patterns
  @junction_patterns
end

#parts ⇒ Array<AffixForm> (readonly)

Returns Parts of the compound word.

Returns:

  • (Array<AffixForm>) —

    Parts of the compound word

Instance Method Details

#junction_pattern(index) ⇒ Readers::CompoundPattern?

The pattern whose replacement rebuilt the junction after part index, if any.

Parameters:

  • index (Integer) —

    Index of the part left of the junction
