Hyphenating prefixes

Prefixes are additional letters or numbers at the front of a word that change it’s meaning.  Examples of common prefixes include: inter, intra, anti, milli, hyper etc. Most common prefixes are not hyphenated (check with a dictionary, or a technical writer).

Prefixes that are hyphenated include chemical terms with an italicized prefix: cis-dimethylethylene, or ß-lactose.

Use a hyphen when the second part of a word starts with the same vowel that the first part of the word ends with; For example, pre-eminent, re-educate, co-opt, semi-invalid, or if the word would be difficult to read without a hyphen; For example, co-author, de-icing.

Intergenerational day, June 1st, is a day that celebrates connections between age groups. This year has been particularly tough for seniors during the pandemic. However, the founder of Edwards Technical Writing, Alison Edwards, was lucky to be able to work from home, and isolate with other generations of her family; Including her dad. Thanks for all the pandemic scrabble games Dad!
