Essential Part — Frequently Asked Questions

An essential part is required for the thing to exist at all. A wheel is essential to a bicycle; a bell is merely commonly attached to one.
What is the single test to apply?+
Say "a ___ without ___ is still a ___". If the sentence is true, the option is not essential. "A book without a title is still a book" is true, so a title is not essential.
