Sorry, Martin,for not giving the basic verb form above
It's still an example of metathysis.
The Future form "innseoidh" becomes "inneosaidh". the dropping of the initial "i" is a different phenomenon altogether.
As I have already said, the Dependant Future form of the verb "abair" changes from "abróidh" to "abóraidh" by the same process.
I'm sure there are other examples, but it's too late at night and I have other work still to do.
Slán go fóill,
