kindled

Kindled is the past tense and past participle of the verb kindle. In common usage, it means to light or ignite something, or to spark or inflame an emotion, interest, or activity. It can describe lighting a fire, or figuratively, awakening curiosity or passion.

The word originates in Old English and is of Germanic origin, with senses historically tied to fire and ignition. Over time, its meanings broadened to include arousing or stimulating non-physical phenomena such as interest, enthusiasm, or affection.

In everyday language, kindled can describe actions and feelings alike. Examples include lighting a campfire (“she kindled a small flame in the hearth”) or stirring emotions and curiosity (“the announcement kindled interest in the project”). The term is commonly used with both tangible and intangible objects.

In scientific contexts, kindling refers to a specific phenomenon in neuroscience and epilepsy research. Repeated stimulation of a brain region can progressively increase its excitability, eventually producing seizures; this process is called kindling, and the resulting epileptic events may be described as kindled. The term is also used metaphorically in other disciplines to describe progressive sensitization to stimuli.
