Usage
Spelling tips for believe The word believe is hard to spell for two reasons. First, because it can be hard to remember the order of the i and e. Sometimes people want to spell it beleive, which is incorrect. Second, because it is pronounced [ bih-leev ], which makes you think there may be a second i in the word, as in bilieve. How to spell believe: The easiest way to remember how to spell believe is with the classic mnemonic device: “I before E, except after C." Believ[ing] is an important part of "being alive", which reminds you that the first syllable is be, not bi.

Explanation
If you believe something, you think it’s true. If you are easily duped then you might believe your little sister when she says a thief broke into the house and ate all your candy. Believe comes from old German words meaning to have trust. Belief doesn’t require proof, just acceptance. If you’re on a jury and the prosecution and defense present two different versions of what happened, you have to decide which side you believe. To believe can also mean having confidence. If you believe in me, it doesn’t mean that you think I’m real (unless I’m a ghost). It means you think I can do what I set out to do.
