Embedding refers to the process of inserting one sentence into another sentence. It includes putting questions into affirmative sentences, with a subsequent change in word order (embedded questions).
'I wonder if you could tell me what time it is?' is the question 'What time is it?' embedded in a polite structure. 'He asked me if I wanted to have a drink' is another embedded question, this time in reported speech.
In the classroom
Learners need opportunities for recognising embedded questions as questions and practice in changing word order when they use the form.
