The clipped words in the database were compiled from various published sources, websites, a survey that was conducted within the project, and from personal observations. For each entry in the database, a primary source is identified. Secondary sources are identified for clippings that were attested across different publications and websites.
A substantial number of clippings are listed in the online edition of the Oxford English Dictionary (OED). We retrieved words that were characterized as shortened forms in their respective entries, which also identify the corresponding full forms. Another rich source of clippings is An English-French dictionary of clipped words (Antoine 2000). Among the academic studies of clipping as a word formation process that we consulted, Marchand (1969), Lopez Rua (2002), and Jamet (2009) proved particularly useful. Moving on to online resources, on Wikipedia (www.wikipedia.org), several lists of shortened words are available, which we cross-checked with the entries from other published sources.
