All the classes which occupy a particular position in a sequence or construction or in a group of partially similar construction types may be said to have a feature of meaning in common: Hebrew 'H' (which includes 'C' and 'K' […]) in 'RpH' may be said to have the meaning of ‘word inflection’. In some cases the participants in a particular position of a given construction have such common meanings as ‘plural’, ‘object (of transitive verb)’ […]. These would be examples of what may be called semantic categories of the grammar.
