Tricky and slippery both describe someone dishonest and hard to trust. Tricky stresses using tricks or schemes to deceive, often describing crafty people, plans, or scams.

这两个词都能形容不诚实、让人无法信任的人，但侧重不同：tricky 强调耍手段、用花招骗人；slippery 强调难以捉摸、说话躲躲闪闪、靠不住。这里不比较 tricky 表示“（问题）复杂难解”的意思，也不比较 slippery 表示“（表面）滑的”的意思。
