More difficult or complicated than expected; more likely to deceive or confuse.
From 'tricky,' which derives from 'trick' (from Old French 'trique'). The comparative form adds '-er' to compare degrees of difficulty or deceptiveness. The word evolved from meaning literally deceiving to meaning generally difficult or requiring skill.
The word 'trick' originally meant a deceptive move, so 'trickier' literally means 'more deceptive'—even when we use it to describe a tough math problem, we're saying it's trying to fool us!
