*[AUTHOR’S NOTE: Here is the quotation I was assigned by Marigold.  It was translated into Sindarin for me by Ithildin:

 'May he be brave, and have the strong head to think with, and the strong heart to love with, and the strong hands to work with, and the strong feet to travel with, and always come safe home to his own.' ” From “Five Children And It” by Edith Nesbit ]

And here are the notes on the translation, provided for me by the very kind and talented Ithildin:

 No e beren, ar garo i dhôl vell na nauthad, ar i ind vell na velad, ar i gaim vell na gared naid, ar i dail vell na drevaded, ar lúban tolo beriannen na mar în.

9.2.3 Imperative of ’to be’

There are few situations where the context is not sufficient to allow what form of ’to be’ needs to be filled into a given ’gap’. One of these situations is the imperative. Here, the form  no!  (be!) is written explicitly.

No veren! (Be bold!)

Most likely, this no has evolved beyond a mere imperative into a particle denoting optative, which might be translated as ’may it be that’.
