spontaneous
Done without planning
Spontaneous describes actions or events that arise naturally, without planning or external cause.
A spontaneous decision happens on impulse; spontaneous applause breaks out without prompting.
In science, spontaneous processes occur without outside intervention—spontaneous combustion, spontaneous generation.
The word suggests authenticity and naturalness, free from calculation or rehearsal: Her laughter was completely spontaneous.
