תִּתְחַדֵּשׁ!

Commonly pronounced titchadesh in casual speech. It is often used to address one person, especially a man, informally.

תִּתְחַדֵּשׁ! is a friendly Hebrew expression used when someone gets something new, especially clothes, shoes, or another similar personal item. It is similar to saying “May it bring you joy!” or “Enjoy your new purchase!” The phrase is usually said after someone buys or receives something new, and it carries a warm, congratulatory tone. The supplied example, תִּתְחַדֵּשׁ עַל הַחוּלְצָה!, shows this everyday use clearly: “Enjoy your new shirt!” The preposition עַל is commonly used in this kind of expression before the item being celebrated. This is not a literal command in normal conversation. It is a set expression of good wishes, especially in casual social situations. If you are speaking to a woman, a different form is typically used: תִּתְחַדְּשִׁי!

The form is the masculine singular imperative, used here as a fixed expression. For a female addressee, the corresponding form is תִּתְחַדְּשִׁי. In common use, the phrase often appears with עַל + the item, as in תִּתְחַדֵּשׁ עַל הַחוּלְצָה.

This expression is especially common in Israeli Hebrew when someone wears or buys new clothes or shoes. It is part of everyday politeness and friendly small talk.
