A little knowledge is a dangerous thing.
A little knowledge is a dangerous thing.
Meaning in plain English
The saying calls a little knowledge dangerous. It warns that partial understanding may be mistaken for enough understanding to act confidently.
Example
A learner recognises the limits of an introductory explanation before applying it to a complex task.
Deeper explanation and when to use it
Little does not identify an amount or subject. A useful application asks what remains unknown and whether further checking is needed. It should not discourage beginners from learning or assume that limited knowledge always causes harm; the issue is how a person uses it.
When to use it
Use it to discuss the limits of partial understanding.
Keep in mind
Beginning to learn is not inherently dangerous, and no particular harm is established.
