IPA: /ˈkæniər/
KK: /ˈkæn.i.ɚ/
More careful and shrewd in making decisions or judgments than others.
She was cannier than her competitors, always finding the best deals.
Cannier → The word 'cannier' is derived from 'canny' (from Scottish 'canny', meaning shrewd or careful) with the comparative suffix '-er' (indicating more). Thus, 'cannier' means more shrewd or more careful than another.
Think of someone who is 'shrewd' or 'careful' ('canny') and then imagine that they are 'more' so ('-er'). This helps you remember that 'cannier' means more shrewd or careful.
