What does ignite mean?
Ignite means to set something alight or cause it to catch fire. It can also describe the beginning of a strong emotional, political, or intellectual response: a speech may ignite debate, a performance may ignite enthusiasm, or a report may ignite controversy. The literal sense is immediate and physical, while the figurative sense emphasizes sparks, rapid development, and intense consequences. The word is common in British and American English and is often more vivid than a neutral alternative such as “start” when describing fire or a dramatic response. In figurative uses, it typically carries a sense of intensity, making it especially suitable for events that rapidly attract attention or produce strong reactions.
To set fire to something or cause it to catch fire; to begin burning.
"He ignited the barbecue and waited for the coals to become hot."
Often transitive, taking the material or object that catches fire. It can also be used intransitively, especially in technical contexts.
