1. I was looking at the word "design" for its usage in the Collins Cobuild Advanced Learner's English Dictionary and the dictionary had this definition and an example of its usage. What baffles me is why the example has the article "a" when that article is usually reserved for a countable noun, as far as I know. Help.
Design: an uncountable noun
The design of something is the way in which it has been planned and made usually with suppliement.
a new design of clock.
2. I think you have covered this area of grammar several times before, can you tell me why the person would use the artlcle "a" in front of the word "director" when the article "the" or no article seems to be appropriate?
He is a director of ZZ Certificate Program.
