Meaning
Cannot be achieved without / There is no ~ unless ~ exists Used to state that something is absolutely indispensable for a result to occur.
Formation
Noun + なくして + は / も + Verb (negative)
Explanation
なくして〜ない is a formal, logical expression used to say that a certain condition is essential, and without it, the result is impossible.
It strongly emphasizes necessity, not probability.
Key nuance:
The speaker presents a logical dependency
The result is completely impossible without the condition
No emotional tone — purely objective and reasoned
Common in:
policies
academic writing
business analysis
JLPT N1 reading passages
This grammar often appears in statements explaining:
success
achievement
realization of goals
existence of outcomes
It sounds stronger and more absolute than expressions like なしには.
