[2] Such etymologies often have the feel of urban legends and can be more colorful and fanciful than the typical etymologies found in dictionaries, often involving stories of unusual practices in particular subcultures (e.g. Oxford students from non-noble families being supposedly forced to write sine nobilitate by their name, soon abbreviated to s.nob., hence the word snob).
For a given word there may often have been many serious attempts by scholars to propose etymologies based on the best information available at the time, and these can be later modified or rejected as linguistic scholarship advances.
The etymologies of humanist scholars in the early modern period began to produce more reliable results, but many of their hypotheses have also been superseded.
Other false etymologies are the result of specious and untrustworthy claims made by individuals, such as the unfounded claims made by Daniel Cassidy that hundreds of common English words such as baloney, grumble, and bunkum derive from the Irish language.
[5][6] In the United States, some of these scandalous legends have had to do with racism and slavery; common words such as picnic,[7] buck,[8] and crowbar[9] have been alleged to stem from derogatory terms or racist practices.
