A compound construction is a construction consisting of two strictly adjacent slots for °roots that cannot be expanded by °full-nominal or °adjectival °modifiers, or by °degree qualifiers.
The definition is adapted from Haspelmath (2025: 1).
compounding (STR) = a strategy for encoding the relation in major propositional acts (modifier–referent, predicate–argument), in which the two elements are combined in a single word. Example: in doorknob, door and knob form an instance of compound- ing. The term ‘compounding’ or ‘compound’ is also used for the typifying construc- tion and the binominal lexeme construction.
