A fairly accurate description I stumbled upon...
As your dominant function, Ne makes you a person who is interested in the world around you. In one way, Ne is curiosity. But it is not just the details of the world that interest; it is how, behind those details, there is a bigger picture or larger pattern. And so another way, Ne is brainstorming. You can leap from a few immediate cues to a quick impression of the whole. To you, the bigger pattern was always there, waiting for someone to discover it.
For example, given enough elements to suggest a star or a square, you have a hard time not filling in the blanks and seeing the compete image. Whatever you find, there is something more to find: a broader context, a whole, which will change your understanding of the part. And once you've grasped a whole pattern, you can envision options that don't yet exist.
You see the outer world as having whole range of possibilities and meanings, and with them a range of different paths to follow. Your Ne function helps you think 'outside the box' and go beyond traditional or currently accepted assumptions and beliefs to develop innovative new ways of seeing and doing. Ne continually welcomes the unknown, and is always ready to adjust in unforeseeable ways.
Supporting and balancing your dominant, outwardly-directed Ne is your inner-focused auxiliary function of Introverted Thinking (Ti). Your Ti sees the world as a question to be answered and life as a journey towards understanding. Ti wants – needs – to know how things work.
But Ti is about more than just 'theory'. Through direct, firsthand experience, your Ti will seek a clear visual picture of how different parts of a system work together. Your Ti will often lead you to take things or ideas apart so as to understand how they work; Ti knowledge comes through the fingers, not through the ears or the eyes.
The Extroverted Feeling function seeks social connections and strives to create harmonious interactions with others. Fe responds to the other's needs, expressed and unexpressed, and prompts a person to adjust their behavior to serve those needs. Evidence of Fe is seen through the 'social graces', such as being polite, being nice, being friendly, being considerate, and being appropriate.
As an inferior function Si can lead an ENTP to working longer and harder but less effectively; chronic anxiety and persistent feelings of sadness and despair; loss of enthusiasm and motivation combined with social withdrawal; and the continual imagining of new possibilities in your life but without any follow-through.
