The alphaDictionary Historical Dictionary of American Slang presents a unique way for studying slang. It contains over 2200 slang words with the centuries in which they were first printed. The dates were taken from the Oxford English Dictionary, the Online Etymological Dictionary, or the earliest occurrences our editors can remember in the case of recent terms. (If you are not sure what slang is, click here.)

The dictionary can be searched for slang words, their meanings, and dates.

To find a specific slang word, type it in the "Word" box.

To access all the slang terms meaning "to leave", type Leave in the "Search" box.

in the "Search" box. To access all slang originating in the 1920s, just type in 1920 in the "Beginning Year" field.

in the "Beginning Year" field. To limit any search to specific years, add the beginning and ending years in the appropriate boxes.
