More About Spontaneous

What does spontaneous mean?

Spontaneous means natural and unplanned. When you describe an action or event as spontaneous, it means it happened naturally, without having been planned, as in The meeting turned into a spontaneous dance party.

When something that someone does is described as spontaneous, it means it was done out of a natural impulse, without having been thought about beforehand

When spontaneous is used to describe a person, it means they have a tendency to or are known for doing things impulsively and without planning. This is usually used in a positive way to portray them as a fun person who is adventurous and willing to do things on the spur of the moment. Telling someone to be more spontaneous means you want them to be more flexible and willing to do more things on a whim instead of needings for things to be completely structured or scheduled.

The state or quality of being spontaneous is spontaneity.

In a scientific context, spontaneous is used to describe effects that happen independently, without being acted on by outside forces. The most well-known example of its use in this sense is in the term spontaneous combustion, in which something catches on fire due to an internal chemical reaction (as opposed to external ignition).

Example: Julian’s friends knew him as a spontaneous guy who was always up for going on random adventures.

Where does spontaneous come from?

The first records of the word spontaneous come from the mid-1600s. It comes from the Late Latin word spontāneus, which is related to the Latin spont(e), meaning “willingly” or “voluntarily.”

When you describe someone as spontaneous, it implies that they’re “up for anything”—they’re willing to try something new at a moment’s notice (without needing to plan or prepare for it). Telling someone who’s going on vacation to “plan to be spontaneous” sounds like an oxymoron (a contradiction in terms), but it really just means that they should reserve some time that is not planned out, when they can choose to do whatever you want.

When someone makes a spontaneous speech, they are speaking without having planned what they were going to say. More common synonyms for this are impromptu, extemporaneous, offhand, and off-the-cuff.
