Explanation
Blocking is the competition through which an established form prevents or strongly disadvantages an otherwise expected new formation. An irregular word may occupy the function for which a regular alternative could be derived. The effect is rarely absolute: frequency, semantic difference, register, and context may permit both forms. Blocking is therefore not a mysterious prohibition but an outcome of lexical competition, specificity, and conventionalisation. The conceptual movement first generates a formally possible candidate, identifies the established competitor, and uses actual distribution to test when its presence suppresses the innovation and when functional differentiation releases it.
Movement of thought
1. A productive morphological rule generates a formally expected candidate for a particular meaning. 2. The lexicon already supplies an established, often more specific or frequent form in the same domain. 3. The candidates compete, and conventionalisation weakens or excludes the newer regular formation. 4. A counter-test searches for semantic, register, and contextual differences separating apparent doublets. 5. Corpus evidence and judgement reveal complete blocking, partial competition, or emerging coexistence.
Scientific use case
Morphology, psycholinguistics, and corpus linguistics investigate blocking through productivity tests, frequencies, and acceptability judgements. Meaning and register require control so division of labour is not mistaken for prevention.
Example
A regular derivative is formally possible under the language's pattern but is replaced in neutral use by a frequent irregular form. The expected innovation may still appear humorously.
Counterexample
Rarity of a possible form does not prove blocking; it may be semantically unsuitable or its pattern unproductive. If two forms have different meanings, they need not compete for the same position.
Distinction
Distinguish blocking from morphological unproductivity, phonological impossibility, synonymy, and rarity alone. It requires competition between an established form and an otherwise expected formation in the same functional domain.
Effect on thought and perception
Blocking preserves established forms and constrains otherwise productive patterns. It reveals competition between memory and rule and explains many gaps in apparently regular paradigms.
Resonance
A possible form finds its position already occupied. The existing word sounds so strongly in the lexicon that the new formation recedes unless another context opens space.

Historical background
Aronoff’s Word Formation in Generative Grammar characterizes blocking through the non-occurrence of one form because another already exists. His English examples concern -ity derivatives competing with established related nouns; -ness derivatives behave differently in the account. This theoretical witness connects lexical competition with specific morphological conditions. It does not establish an unrestricted blocking rule for German word formation.
How conceptual history changes the analysis
A blocking analysis needs a possible formation, a competing established item and evidence connecting their distributions. Mere absence of a form is insufficient.
