Oh look, it's a dain.

[R. Sale]

I simply would like to express my surprise to find that 'dain' is a word that is actually a valid part of French vocabulary. Not sure how much it is still in use and if a VMs connection was previously made. Is the word 'dain' as an equivalent of 'fallow deer', an actual part of the VMs narrative? That seems unlikely. Does it have some other meaning or purpose? That is not yet known.

Helmut's proposal is interesting and as Koen suggests, what is needed are more examples. Abbreviations occur frequently in liturgical calendars. In Latin and highly formulaic I presume, though I don't know them, they are probably familiar to interested investigators.

What needs to be done to advance the investigation of abbreviations?
