The vocabulary of languages ??includes different elements in terms of morphology, syntax and semantics. It is accepted that the vocabulary of Turkish mostly consists of core words, idioms, compound words, formulaic expressions, proverbs and reduplications. However, the vocabulary elements of languages ??are not limited to these. The vocabulary of Turkish can also include different elements beyond these. The most important of these are collocations, binomina, verb sequences, biverba, lexical and grammatical frames. Although reduplications are defined with their specific features in Turkish language studies, sometimes different vocabulary elements such as idioms, collocations, as well as repetitions, verb sequences, hendiadyoin or binominal and biverba, units with more than two words have been referred to as reduplications. Reduplications have been a problematic term and field of study in terms of both terminology and content and have been used as a grammatical dustbin category. Different vocabulary and grammatical elements have been considered as reduplications in terms of their rough formal features in Turkish language studies. In particular, elements defined with the terms of double repetitions and triplets, quadruplets, quintuplets are often grouped under the umbrella of reduplication together with the other elements in question. Especially binomina and biverba referred to with the term hendiadyoin and repetitions are mostly seen as the same. However, while repetitions are a grammatical structure and expression, fixed double nouns and verbs are a lexical unit. The term reduplication has also been used to include verb sequences and double verbs that develop from sequential sentence structures. While verb sequences are multi-word and syntactic phenomena, biverba are lexical and grammatical units formed under the influence of lexicalization and grammaticalization. The term reduplication should be distinguished from different vocabulary elements and should be limited to certain vocabulary or grammatical elements. In this study, it has been argued that formulaic binomina and biverba, namely hendiadyoin and verb sequences, are different from repetitions, that it is no longer possible to cover these dissimilar lexical and syntactic categories with the term reduplication, and that the lexical and grammatical elements in question can be distinguished with certain criteria
