As much as Aegon Targaryen does? (I'm saying this Aegon to avoid spoilers)
From the tips and notes on declension in the Pos. Adj. skill: "When a nasal consonant (either n or m) is followed immediately by r, the nasal is deleted, and the previous vowel lengthens. In addition, a homorganic voiced nasal (d for n and b for m) appears in between the vowel and the r. Thus, what was originally konra became kondra and then kōdra."
Essentially, "mr" is illicit in Valyrian, so it becomes "br" with a lengthened vowel beforehand.
My question was for a lesser word for "love", but i guess "vaoresas" is the answer.
Is there anything he to say the his refers to the boy? Because in english this could distinctively mean another "he".
