The world is made up of many cultures and customs, and It is always nice to be considerate of cultures other than your own. In today's podcast you will learn how to ask if it's normal to wear shorts.
The word (annaas - the people) is considered as a feminine word, so you use the feminine prefix of the present verb with it which is (ta).
You say: Ahmed yasta3'rib (Ahmed is masculine)

So as the word (annaas) is considered feminine then it takes (tasta3'rib).
Thanks for your nice lessons
