If you cite definitions you have to mark them as citations and give a source. Otherwise you are plagiarising.
Guidelines for formatting glossaries:
- arrange entries alphabetically
- if the entry is a phrase, give it in its natural order (software development) rather than reversed (development, software)
- non-letter characters precede "a" in ordering
- show alternative spellings in parentheses
- if a term has more than one definition, number the definitions
question (Q). (1) What you ask if you don't know the answer. (2) A post type on Stack Exchange sites.
Contrast with: answer. See also: tour; off topic.
Explanation of example:
In the example, "Q" is an alternative spelling for "question". "(1)" and "(2)" signify different definitions. After a linebreak, "Contrast with:" gives the opposing concept and "see also:" points out related definitions.
I only have access to an old guide from the early 90s, so the formatting may have changed. If you can verify or falsify, please comment or edit.
