Explanation
The morphological head is the constituent of a complex word formation that determines central grammatical properties of the whole and often supplies its basic semantic class. In a German determinative compound, the right-hand constituent typically determines word class, gender, and inflection, but head position differs across languages. Some formations are exocentric and lack an internal semantic head. Headedness is therefore not merely a matter of spatial position. The conceptual movement tests feature inheritance, categorial membership, and semantic relation, then asks whether a competing morphological analysis or language-specific rule captures the structure more accurately.
Movement of thought
1. The constituents of a complex formation are described by word class and grammatical features. 2. Inflection, gender, or category of the whole reveal possible directions of feature inheritance. 3. A semantic test asks whether the whole denotes a subtype of the proposed head. 4. Language-specific positional rules are examined without treating them as a universal definition. 5. Exocentric and ambiguous formations provide counterevidence for the selected analysis.
Scientific use case
Morphology, typology, computational linguistics, and lexicography use headedness tests to analyse complex words. Cross-linguistic work examines head position, feature percolation, and exocentric exceptions through explicit criteria.
Example
In a newly formed compound, the second constituent determines gender, plural, and classification as a device. The first constituent merely narrows the field of work for which the device is intended.
Counterexample
The final or most salient constituent is not automatically the morphological head. If it determines neither the grammatical category of the whole nor its semantic class, another or exocentric analysis must be considered.
Distinction
Distinguish the morphological head from a syntactic head and from linear position alone. It is identified through grammatical and semantic feature inheritance within word formation, and those criteria may diverge.
Effect on thought and perception
The head organises a complex form by determining what the whole counts as grammatically and often semantically. This order makes innovations interpretable but may conceal exceptional structures.
Resonance
Not all parts of a word formation carry equal weight. One constituent gives the whole direction and category, while the others tune its shape more precisely.

Historical background
Jespersen describes a chief element modified by other elements in a composite expression. His analysis of ranks provides historical background for identifying a head, but the discussed combinations are principally syntactic. The Atlas’s morphological-head profile concerns structure within words, where the criteria for headedness require separate testing. Category, semantic type and inflectional behaviour do not always identify the same element. This distinction prevents an attractive tree diagram from serving as proof of one universal kind of dependency. Jespersen’s witness helps articulate the general question of which component determines a larger expression’s character. It cannot establish the later morphological terminology or resolve exocentric compounds. A complete history needs direct accounts of word structure and their proposed diagnostics.
How conceptual history changes the analysis
A morphological head must be established by explicit diagnostics such as category, inflection, and semantic type; Jespersen’s syntactic ranks provide only the neighbouring general idea.
