What is the meaning of discussing?
to consider or examine by argument, comment, etc.; talk over or write about, especially to explore solutions; debate: to discuss the proposed law on taxes.
How is an pronounced?
A becomes a (ay), and an becomes an (aan). And if we’re saying the letter of the alphabet, we say Ay. What about the? Again, we don’t normally stress that either, but sometimes we can and then the pronunciation changes to the (thee).
