Unclearness is a type of vulnerability where the expert can't plainly separate between two unique classes, for example, 'individual of normal tallness.' and 'tall individual'. This type of unclearness can be demonstrated by some minor departure from Zadeh's fluffy rationale or emotional rationale. Equivocalness is a type of vulnerability where even the potential results have indistinct implications and translations. The assertion "He gets back from the bank" is uncertain on the grounds that its translation relies upon whether the word 'bank' is implied as "the side of a waterway" or "a monetary foundation". Equivocalness commonly emerges in circumstances where various investigators or spectators have various understandings of a similar statements.[citation needed]
