1. The Arabic word "Ma" is a wonder word that has so many meaning. It sound confusing for a learner like me and I thought it was odd until we think of similar situation in English, which we tend to take it for granted. In this case 'ma' is meant to be a question form and can be translated as "what".
2. The pronoun "ka" or "ki" is possessive pronoun, the like of "your". In arabic many of the words changes according to 'gender' and many other criteria.
3. In English , we learn about singular and plurals. However the Arabic has singular, two and plurals.
