Common mistakes	Confused with 'ignition', which is the mechanism that starts a fire., Used incorrectly in passive form; 'ignited by' should specify the agent., Thinking it can only be used for physical fire.	Confused with 'lite' which means lower in calories., Used as a verb when it should be a noun., Forget to use articles like 'a' or 'the' when referring to light.	Confused with 'sparkle' – remember 'spark' is singular., Using 'spark' as a verb incorrectly – ensure you're using it as a noun in certain contexts., Adding unnecessary articles – 'a spark' is correct, but some learners say just 'spark'.	Using 'trigger' without an object (e.g. 'The noise triggered' instead of 'The noise triggered a reaction')., Confusing with 'triggered' as a noun., Mixing up with 'impact' or 'affect' too broadly.
Usage notes	Often used for literal fires but can also describe sparking ideas or emotions. Avoid in overly formal contexts.	Use 'light' when talking about brightness or when referring to weight. It's appropriate in both spoken and written English, but in creative writing, you might also use it metaphorically.	Use 'spark' when referring to a small flame or bright light. It's appropriate in most contexts, but avoid using it in very formal writing where alternatives like 'ignition' might be preferred.	Commonly used in both casual and formal contexts. Often used to describe a cause-and-effect relationship, especially in psychology or discussions about emotions. Avoid when discussing less serious or trivial matters.
