Lisalõpuga

Lisalõpuga is a term used in Estonian linguistics and language education to describe a word form that has been extended by an additional suffix. Literally, it combines lisa 'additional' and lõpp 'ending' or 'suffix'. The label is employed mainly in metalinguistic explanations rather than as a formal grammatical category. It helps learners and researchers discuss how a base form can be modified by attaching more than one suffix, resulting in an expanded or altered grammatical meaning.

In practice, lisalõpuga is used to describe suffix stacking—where several endings are added to a stem to express various grammatical relations such as case, number, mood, or derivation. The concept is common in pedagogical grammars and corpus annotations, where a form may be described as base plus lisalõpp to indicate the presence of an additional ending beyond the basic inflection.

Relation to related concepts: it is connected to derivation and inflection in Estonian morphology and to the general idea of affixation. It is not considered a separate part of speech but a descriptive label used in specific studies. Some linguists stress that the term should be clearly defined within each context, since what counts as an 'additional ending' can vary by dialect, register, or teaching tradition.

In summary, lisalõpuga serves as a practical label for discussing how words can acquire extra endings, aiding analysis and instruction in Estonian language studies.
