Handlingand
Handlingand is not a recognized concept in standard dictionaries or established academic disciplines. In most cases, it appears to be a typographical error or a concatenation of two words, "handling" and "and," rather than a term with defined meaning. The lack of formal usage means there is no agreed definition.
Possible origins include typographical error during manual entry, optical character recognition (OCR) misreading of "handling and"
Common interpretations when encountered in text: either it should be "handling and" as part of a phrase
