A misplaced modifier occurs when a word or a phrase is incorrectly placed in a sentence that separates it from the word it modifies, making the sentence have a different meaning.
Therefore, correcting the misplaced modifier in the sentence "We saw three lion cubs using binoculars", we change it to "Using binoculars, we saw three lion cubs"
This is because, from the first sentence, it seems like the cubs were using binoculars, when in actual sense, it was the speaker that used binoculars to see the cubs.
