I would like to know how to express,
'May you live in peace and love.'
and I wish that for you, as well.
“May you live in peace and love! “ translates as follows:
-“Utinam in pace et amore vivas!”, if you are addressing to only one person.
-“Utinam in pace et amore vivatis!”, if you are addressing to many persons.
Please read more below.
All the best,
-May =UTINAM ( adverb which must be followed by the subjunctive)
-you live =VIVAS (2nd.person singular, present subjunctive of VIVO, I live) or VIVATIS (2nd.person plural, present subjunctive of VIVO)
-in = IN (preposition which takes the ablative)
-peace = PACE (ablative singular of PAX, 3rd.declension)
-and = ET
-love= AMORE (ablative singular of AMOR, 3rd.declension)
As you can see, Latin word order order can be variable as Latin is an inflected language where synctactical relationships are indicated by the ending, not by the order of the words.
