If you know a bit of Hebrew, you’re probably familiar with the word for please – בְּבַקָּשָׁה (be-vah-kah-SHAH). When saying please, we’re actually saying, I’d like to have some of that! Likewise, the economic term for demand is בִּקּוּש (bee-KOOSH) – formed from the verb לְבַקֵּש (le-vah-KESH) – to ask for something/ to request.
If you know some more Hebrew (I think this word is in our Level 3 course), you know that to offer or to suggest is לְהַצִּיע (le-hah-TSEE-ah). So while an offer is a הַצָּעָה (hah-tsah-AH), supply – as in “there is a huge supply of therapists on Ventura Blvd. in the San Fernando Valley” – is הֵיצֵע (heh-TSEH-ah).
So supply and demand are היצע וביקוש.
