What is a good Greek word for “Subtle” as in “can you try to be more subtle when you talk about this?” When you’re talking about a sensitive subject any other person is coming on too strong.
The closest equivalent I can think of in Greek, in the sense of being more careful, tactful and not too overt, is "διακριτικός". Its direct translation is "discreet" but given the context, I think that in this case it suffices as a translation for "subtle".
διακριτικός, -η, -ο
2. που φέρεται με διακριτικότητα, που δείχνει ιδιαίτερη προσοχή και λεπτότητα , ώστε να μην παραβιάσει την ιδιωτική ζωή των άλλων, να μην προσβάλλει τις ευαισθησίες τους και γενικότερα να μην τους ενοχλήσει
Highly valued in Greek social interactions, especially in professional and family contexts. Being διακριτικός is considered a mark of good upbringing and social intelligence. Often used when discussing sensitive family matters or workplace dynamics.
