TERMINOLOGY:

-- "slot" = A particular combination of case/number. Example slot names for nouns are "gen_" (genitive singular) and "voc_p" (vocative plural). Each slot is filled with zero or more forms.

-- "form" = The declined Ukrainian form representing the value of a given slot.

-- "lemma" = The dictionary form of a given Ukrainian term. Generally the nominative masculine singular, but may occasionally be another form if the nominative masculine singular is missing. ]=]

--[=[ Propagate `property` (one of "animacy", "gender" or "number") from nouns to adjacent adjectives. We proceed as follows: 1. We assume the properties in question are already set on all nouns. This should happen in set_defaults_and_check_bad_indicators. 2. We first propagate properties upwards and sideways. We recurse downwards from the top. When we encounter a multiword spec, we proceed left to right looking for a noun. When we find a noun, we fetch its property (recursing if the noun is an alternant), and propagate it to any adjectives to its left, up to the next noun to the left. When we have processed the last noun, we also propagate its property value to any adjectives to the right (to handle e.g. лунь польовий "hen harrier", where the  adjective польовий should inherit the 'animal' animacy of лунь). Finally, we set the property value for the multiword spec itself by combining all the non-nil properties of the individual elements. If all non-nil properties have the same value, the result is that value, otherwise it is `mixed_value` (which is "mixed" for animacy  and gender, but "both" for number). 3. When we encounter an alternant spec in this process, we recursively process each alternant (which is a multiword spec) using the previous step, and combine any non-nil properties we encounter the same way as for multiword specs. 4. The effect of steps 2 and 3 is to set the property of each alternant and multiword spec based on its children or its neighbors. ]=] local function propagate_properties(alternant_multiword_spec, property, default_propval, mixed_value) propagate_multiword_properties(alternant_multiword_spec, property, mixed_value, "nouns only") propagate_multiword_properties(alternant_multiword_spec, property, mixed_value, false) propagate_properties_downward(alternant_multiword_spec, property, default_propval) end
