The words in a dictionary are typically listed in alphabetical order. It makes the finding of the specific word easy. A dictionary is a tool providing with the etymological and grammatical knowledge of the words of a specific language. It has different types. Some dictionaries show the pronunciation by International Phonetic Alphabet or phonemes, while others use the alphabets to make the pronunciation sounds. There are English dictionaries, bilingual dictionaries, e.g., English to French Dictionary, dictionaries for specialized areas, e.g., medicine and geography.

The dictionaries sometimes are categorized according to the level of their users. For example, a dictionary for kids omits the words that are used by adults. In the same way, high-level dictionaries are meant for scholars and adults containing all the words along with their detailed information. Some of the dictionaries are limited to word meanings, while others explain the word’s usages, parts of speech, etymology, and other aspects of a word. Furthermore, a dictionary can be a general dictionary and a specialized dictionary. The specialized dictionary includes words related to specific fields, i.e., medicine, business, IT, etc.

Thesaurus is arranged alphabetically, conceptually, or thematically (words having similar meanings are listed together). A thesaurus gives a list for a choice of words in each entry. It acquaints with the similarities between words and helps in choosing the exact word that better fits within the context. It is commonly used by writers to avoid monotonous in a writing piece. People belonging to the professional fields, e.g., scholars, take the help of Thesaurus to deliver high-level information.
