diction - print wordy and commonly misused phrases in sentences
diction [-b] [-d] [-f file [-n|-L language]] [file...]
diction [--beginner] [--ignore-double-words] [--file file [--no-default-file|--language language]] [file...]
Diction finds all sentences in a document that contain phrases from a database of frequently misused, bad or wordy diction. It further
checks for double words. If no files are given, the document is read from standard input. Each found phrase is enclosed in [ ] (brack-
ets). Suggestions and advice, if any and if asked for, are printed headed by a right arrow ->. A sentence is a sequence of words, that
starts with a capitalised word and ends with a full stop, double colon, question mark or exclaimation mark. A single letter followed by a
dot is considered an abbreviation, so it does not terminate a sentence. Various multi-letter abbreviations are recognized, they do not
terminate a sentence as well, neither do fractional numbers.
Diction understands cpp(1) #line lines for being able to give precise locations when printing sentences.
Complain about mistakes typically made by beginners.
Ignore double words and do not complain about them.
Suggest better wording, if any.
-f file, --file file
Read the user specified database from the specified file in addition to the default database.
Do not read the default database, so only the user-specified database is used.
-L language, --language language
Set the phrase file language.
Print a short usage message.
Print the version.
On usage errors, 1 is returned. Termination caused by lack of memory is signalled by exit code 2.
The following example first removes all roff constructs and headers from a document and feeds the result to diction with a German database:
deroff -s file.mm | diction -L de | fmt
specifies the message language and is also used as default for the phrase language. The default language is en.

There has been a diction command on old UNIX systems, which is now part of the AT&T DWB package. The original version was bound to roff by
enforcing a call to deroff. This version is a reimplementation and must run in a pipe with deroff(1) if you want to process roff docu-
ments. Similarly, you can run it in a pipe with dehtml(1) or detex(1) to process HTML or TeX documents.
