Translation request

Hello all, looking for assistance with the translation into Sindarin for:

Darkdawn

I'm not sure if it's appropriate to combine the words for Dark & dawn, and if so, it would modify the words.

Thanks in advance

Mae govannen Lindsay,

For darkdawn it depends on with dark you want.

• dûr [nd-] adj. “dark (with evil implications), gloomy, hellish”
• S., N., ᴱN. fuin n. “night, gloom, darkness, [N.] dead of night”
• S., N. môr n. “dark(ness); †night”

And dawn is already a compound S. minuial, n. “(dawn) twilight” of min “one” and uial “twilight”

So you could have:

• Duruial Dark Twilight
• Moruial Dark Twilight

Using fuin yields a very heavy name. So won't offer it.

Amazing. Thank you so much.
