If you spend any time around English speakers, you will quickly notice how often they say sentences that begin with “I wonder…”. These sentences may be said to another person or nobody in particular.
“I wonder…” means “I curious and want to know…”. To make this kind of sentence, follow “I wonder..” with a question word (when / who / what etc). If the question you want to know about is a yes-no question, follow “I wonder.. with if or whether.
For example: I wonder what the weather will be like tomorrow. (I want to know tomorrow’s weather forecast? Does anybody know what the weather will be like?) I wonder who’ll win. (I’m curious about who will win. Who do you think will win?) I wonder what the time is. (Please tell me the time.) I wonder if that price includes sales tax. (I want to know if sale tax is included in the price.)
“I wonder..” statements are an indirect way of asking a question. They are also a great way to promote a conversation and discussion about a topic as these statements invite others to suggest possible answers.
