Explanation
A stem is the base to which inflectional material attaches or on which an inflectional operation acts in a morphological analysis. It may be simple, derived or compound. Stem is therefore not synonymous with root: a stem can contain several meaningful components. In the context of ablaut, a paradigm may also involve different stem shapes. Analysis must specify the relevant form and operation. Merely removing visible endings does not always produce a unique or theoretically neutral definition of the stem.
Movement of thought
1. Compare word forms. 2. Identify the inflectional operation. 3. Isolate its base. 4. Record stem alternations. 5. Analyse internal structure separately.
Scientific use case
Paradigm analysis can document stem forms and their distribution.
Example
In a simple segmentation of German Freundlichkeit-en (“kindnesses”), Freundlichkeit is the inflectional stem although it can itself be analysed morphologically.
Counterexample
The stem of a complex word need not be its smallest lexical base.
Distinction
Distinguish stem from root, lemma, complete word form and an arbitrary letter sequence.
Effect on thought and perception
The stem concept identifies the base of a particular operation.
Resonance
What an ending attaches to may already have a structure of its own.
