Tips

usage
殚 is literary and almost always appears in 殚精竭虑 ('to rack one's brains and exhaust all effort'), describing total devotion of mental energy to a task.

Components

radical
歹 dǎi
bad; bare bone; death
歹 is the 'death/bare-bone' radical. Here it suggests something worn down to nothing - energy spent until totally drained.
phonetic
单 dān
single; alone
单 ('single') gives the exact sound dān. A memory hook: spend until you are down to a 'single' last bit, then it is 殚 - exhausted.
