How to say “seriously” in Hebrew
The Hebrew word for serious is רציני for a male or a masculine object, and רצינית for a female or a feminine object. I’m not sure of its etymology. There is a biblical figure named רצין – Retzin, the king of Aram, but there’s no indication of how serious he was. רציני may have something to do with the root ר.צ.ה – want or desire – but I haven’t found concrete evidence to support this. If the two are related, perhaps the connection between them is intention – being serious about wanting something.
With that hat they won’t take you (a male) seriously.
