Examples:
“Strong solar storms can be dangerous for astronauts in space, and can cause problems for GPS systems and satellites. ... But solar storms can also have more

Did you know?
Innocuous is rooted in a lack of harm: it comes from the Latin adjective
innocuus, which was formed by combining the negative prefix
in- with a form of the verb
nocēre, meaning “to harm” or “to hurt.” It first appeared in print in the early 1600s with the meaning “harmless; causing no injury,” as in “an innocuous gas,” and soon developed a second, metaphorical sense used to describe something that does not offend or cause hurt feelings, as in “an innocuous comment.”
Innocent followed the same trajectory centuries before; its negative
in- prefix joined with Latin
nocent-, nocens, meaning “wicked,” which also comes from
nocēre. This is not to say that
nocēre has only contributed words that semantically negate the harm inherent in the root:
nocēre is also the source of
noxious and
nuisance.
