Turn off is a phrasal verb meaning "cause to stop operating". The particle off can be used before or after the object of the verb.
Phrasal verb
If you've ever read I ran into my old teacher and wondered why anyone would run into a person on purpose, welcome to phrasal verbs. They're idioms hiding in plain sight — short verb-plus-particle combinations whose meanings don't match the words you see. Miss them and English films, news, and casual conversation feel half-translated.
A phrasal verb combines a verb with a particle, a preposition, or both, forming a unit with a non-literal meaning: give up, put up with, come across. They're the single biggest source of native-sounding fluency at intermediate level.
A1 | Elementary | Beginners
If you can say your name, ask Where is the toilet?, and read a simple bus sign — but freeze when someone speaks at normal speed — you're at A1. That's not a problem to fix; it's the level where most learners actually live for a while, and recognising it lets you pick the right material instead of drowning in advanced grammar that wasn't meant for you yet.
A1 is the starting level of the CEFR framework, covering basic everyday communication: greetings, introductions, simple personal questions, present-tense forms of be/have/do, and core determiners and prepositions.
Difficulty: Easy
If a textbook leaves you confused, sometimes the issue isn't the topic — it's that the practice material is layered with extra complications. Filtering by Easy strips that away. You get one rule at a time, in plain everyday language, with no trick questions. It's how you make a shaky foundation solid before stacking more on top.
The Easy difficulty tag marks beginner-level questions and challenges — typically A1 or early A2. Single-rule focus, short sentences, common vocabulary, one clear correct answer.
