Here are some examples of words that are spelled the same but are pronounced differently depending on the context of the sentence. These words can be very confusing for beginning readers.

I want to wind this rope up so the wind doesn’t tangle it.

I need lead for this pencil before I can lead the class.

Also, some words, such as read, look the same whether they are past or present tense but other words, such as lead, are spelled differently as past tense.

I like to read but I’ve read this book already.

I want to lead because you have led long enough.
