Why Use Phrasal Verbs for Discussing Sleep?
Phrasal verbs are common in everyday English, especially in informal and semi-formal conversations. Using them makes your English sound more natural and fluent.
For C1 learners, understanding and using these verbs shows a high level of linguistic competence. They allow you to express nuances about sleep that single verbs cannot.
Phrasal Verbs for Falling Asleep and Staying Awake
These phrasal verbs describe the process of falling asleep or the reasons why you might not be able to sleep.
- Drift off: To gradually fall asleep. This often implies a gentle, unintentional process.

For example, I'm cutting back on sugar means eating less sugar. To cut out something means to eliminate it entirely. For example, I'm cutting out all sugary drinks means stopping them completely.
Can 'build up' be used for positive things related to sleep?
