Neigh

[Rev. Green]

Please explain the second part of this clue by Tees with answer "neigh": "This from the horse's mouth - yet more from mine!"

[Mamyalynne]

From your mouth - sounds like - Nay

nay
neɪ/Submit
adverb
1.
or rather (used to emphasize a more appropriate word than one just used).
"permission to build the superstore will take months, nay years"
synonyms: or rather, and more than that, (and) indeed, and even, in fact, in point of fact, actually, in truth
"it is difficult, nay, impossible, to understand"

[Rev. Green]

Many thanks Mamyalynne, I'd have never thought of that.

[Mamyalynne]

I hope it's right, it made sense to me.

[TheFrogman]

It surely is - and Chambers gives one meaning of the homonym 'nay' as 'yet more'.
