IPA: /ˈbɜːrstiər/
KK: /ˈbɜrstɪər/
Having more bursts or sudden increases in activity or intensity than something else.
The burstier performance of the new engine impressed the engineers during testing.
The word 'burstier' is formed from 'burst' (from Old English 'berstan', meaning to break open or explode) and the comparative suffix '-ier' (meaning more). Thus, 'burstier' means more likely to burst or break open than something else.
Think of something that is 'breaking open' ('burst') and when it is 'more' likely to do so ('-ier'). This helps you remember that 'burstier' describes something that is more prone to bursting.
