Error notation

From Teflpedia

Error notation (/erə(r) nəʊteɪʃən/) is a type of linguistic notation used to notate errors.[1] The most common use is a leading asterisk to indicate an error, however other symbols are also used, though their usage is not universal.

Symbol Symbol name Meaning Example
* asterisk Asserts that which follows was produced but is an error. *"Shane more shorter than Bernie."
? question mark Indicates that the author is unsure whether that which follows is erroneous ?"There are less people in the class than before."
% percentage sign Indicates the author considers that which follows is grammatical only in a non-standard dialect. %"If I wouldn't have gone running, I wouldn't have hurt myself."
# hash Indicates that which follows has semantic or pragmatic weirdness. #"Colorless green ideas sleep furiously."

These can be combined, e.g. #*"Colorless green ideas sleeps furious."

When quoting, especially outside of linguistics, sic is often used.[2]
