Good question; I can't think of anyone (dead or alive) with this first name.

I once heard someone jokingly ask: "Do you know Rembrandt's first name?"

I think we're back ...

Great—it wasn't me firing too many queries then ...

Yes, exactly. So we would expect forms that justify the lemmas dálaid, ·dálai in early texts in the same way other W2 verbs such as erbaid, bádaid, sádaid, rádaid, crádaid (do·accrád(a?)i) with non-palatal consonance—also ·lugai, ·ógai etc.—seem to be more representative of Classical Old Irish? GRMA

e.g. fo·dalet (Sg.), fo·daled (Mon. Tall.). Attested late(r) in Old Irish, I meant. Or should we consider different pre-forms in some cases that make the consonance alternation regular?

Impressionistically, McCone's rule stating that any consonant between historical ā in the root and ī in the ending is expected to be non-palatal, i.e. palatalisation is suppressed, seems to be less systematic with 'l', although this may be solely due to many forms being attested late.

... or is it (partly) based on conventional forms used in other lexical resources (which is valid), including DIL?
