Synonym discussion
Sense: verb/1
All four verbs describe leaving sleep, but they differ in register and feel. 'Wake up' is the everyday choice in conversation: 'I wake up at seven.' 'Awake' as a verb is rarer in modern speech and is most often met as an adjective ('She is awake'). 'Awaken' is the most literary of the group and appears mainly in novels, news writing, and reflective prose; it suggests a calmer, more deliberate moment than 'wake up'. 'Rouse' implies effort or difficulty — you rouse a heavy sleeper or rouse troops at dawn — and often has the feel of stirring someone who does not want to get up. For most spoken situations, choose 'wake up'; reserve 'awaken' for written contexts or for an effect of quiet seriousness.

Etymology
Comes from Old English 'onwæcnan', meaning to spring up or come into being, which later joined with the prefix patterns of 'awake'. The 'a-' prefix was an old way of marking a change of state, so the word originally pictured a person passing into a wakeful state. The figurative use — about feelings or ideas rising in someone — grew naturally from this image of something coming to life.
