Answer:
dynamic.
Explanation:
Adaptability is essential to competent communication because communication is always dynamic.
Adaptability means the ability to adjust to a new thing or to changes in an old thing.
Communication is not new to the world. It is a process of sending and receiving messages or an individual's intent.
Competent Communication is one where the sender (encoder) and receiver (decoder) get satisfied that they've understood each other.
There are different forms of communication - Sign Language, Written notes, Audio means, Video, Telecommunications, Internet channels, etc.
From the examples above, you can tell that communication never stops metamorphosing. It graduates from one to another over time.
For competence in communication, people need to adapt to the ever dynamic channels of communication
