I know that we can and do say كل احترامي (kul i7tiraami; all my respect), but does Arabic have a similar respect-showing expression involving a hat? Many other languages do, like French (chapeau bas), German (Hut ab), and Czech (klobouk dolů). Notice that these languages are from different families.
Furthermore, I know that the Hebrew expression, כל הכבוד (kol hakavod; all the respect), includes no reference to a hat, either. Could it be a Semitic thing?
