Which one do u use more often, the dictionary or the thesaurus?

we need simply meanings of strange or new words in our native language. So we use dictionary for thispurpose. thesaurus serves to see the word substituting the word in question. The deep studiers use the thesaurus as well. But as concerned my self. Dictionary is enough for me to manage to write or understand the English.

I often use the dictionary for word meaning. But, when I want to use another word for the word I use thesaurus. Both are useful tools in writing I even use it to check on the spelling of words I am going to use if I am not sure.
