To do or to make, in Hebrew, is the simple verb לעשות

, as in:

מה אתם עושים הערב?

What are you guys doing this evening? 

– and – 

הם עשו בלגן בחדר.

They made a mess in (their) room.

But the Hebrew expression for “handmade” doesn’t use עשייה

– making, but rather עבודה

– work. The term is עבודת יד

– literally, work of (the) hand. 

For example:

כל המוצרים בחנות הם עבודת יד.

All the products in the shop are handmade.

In this “of” expression (work “of” the hand), the ה

in עבודה

becomes a ת
