indecision
Word family
Synonym discussion
Sense: noun/1
These words all describe a lack of quick or firm choice, but with different nuances. 'Indecision' is a state of being unable to pick between options, often with visible back-and-forth. 'Hesitation' is a shorter pause before action — a person may hesitate for a second but then act decisively. 'Uncertainty' is broader and more internal; it refers to not knowing something rather than not choosing. 'Wavering' focuses on the act of shifting between options, like a scale tipping one way then the other. 'Vacillation' is a formal word for repeated, dramatic changes of mind. In daily speech, 'indecision' and 'hesitation' are most common: 'His indecision cost us the contract' sounds like a long struggle, while 'His hesitation cost us the contract' suggests one moment of delay.
