Here's why:
* Lexicalization refers to the process of making a concept or idea into a single word or phrase. For example, "to have a headache" is lexicalized into the single word "headache."
* Over- as a prefix usually implies an excess of something.
Therefore, "over lexicalisation" would imply using too many words to express a concept that could be expressed more concisely. However, this is not a recognised linguistic phenomenon.
Possible interpretations:
* Redundancy: This is a more common term, referring to using unnecessary repetition or words that have the same meaning.
* Wordiness: This describes writing or speech that uses more words than necessary.
* Formal language: Some languages or writing styles are more formal and use longer, more complex words. This could be perceived as "over lexicalisation" by someone used to simpler language.
