@elmerot @linguistics That is definitely a possibility, but not a certain fact. That etymology would result in two different explanations for #FennoSwedish “mojn” and “morjens” respectively.
The Finnish greeting is discussed in Mikko #Bentlins doctoral thesis on Middle #LowGerman loanwords in #Finnish.

There was more elaborate discussion, behind the link below, on the subject of þ- turning into t- in ”small (commonly unstressed) #FennoSwedish lexemes (rather than d- as in mainstream #Scandinavian).
This development is known from some other periferal dialect areas as well, and from the #Faroese language:
