Cracklier is formed from "crack" (from Middle English "cracchen", meaning to make a sharp noise) and the suffix "-lier" (a comparative suffix indicating more of a quality). The word "cracklier" means having more of the quality of making a sharp noise, often used to describe something that is crisp or brittle.
Think of something that makes a sharp noise ('crack') and remember that 'cracklier' means it makes that noise more than something else.
