What does uniqueness specifies in factor analysis



I am doing a question on factor analysis and after creating the factors.I found uniqueness value of each vector but I am not able to understand how we correlate the value of uniqueness for each variable

Uniqueness gives the proportion of the common variance of the variable not associated with the generated factors.
