For "Significant":

• "Something that happens; happening; occurrence" is a general description of an event, not the meaning of "significant".
• "A striking together; violent contact; collision" is about physical contact, not related to "significant".
• "Flash of insight and understanding; in literature: the moment when a character is suddenly struck with a life - changing realization which changes the rest of the story" is more about an epiphany or a plot - changing moment in literature, not the general meaning of "significant".
• "Having or expressing a meaning" is a more accurate general definition of "significant" as it implies that something has meaning or importance.

For "Unique":

• "The habit or principle of being independent and self - reliant" is about independence, not "unique".

• "One and only; single; sole" accurately describes the meaning of "unique" as something that is one - of - a - kind.
