Liikusinliikusidliikusid

Liikusinliikusidliikusid is a coined expression used primarily in linguistic discussion and online contexts to illustrate complex word formation in Estonian. It is not a standard or dictionary entry but a constructed string that combines several inflected forms of the verb liikuma, meaning to move.

Construction: The sequence appears to assemble forms such as liikusin and liikusid into a single, unsegmented token. In effect, it concatenates alternating verb forms without spaces, creating a long, morphologically dense unit. Because it is not part of normal Estonian usage, the exact interpretation depends on how one reads the embedded forms.

Usage and significance: The expression is used mainly as an educational example to demonstrate how concatenation or reduplication-like processes could produce extended tokens, and as a mnemonic or puzzle in language games. It has appeared in discussions of morphology, word formation, and tokenization challenges in natural language processing.

In computational linguistics and language learning, such constructions are often treated as curiosities or test cases rather than as standard language. They serve to illustrate limits of automatic parsing, segmentation, and morphological analysis when confronted with long, highly inflected sequences.
