· MW
Abbreviations of three letters or longer must be fully capitalized with no periods, including those acronyms pronounced as a single word.

Avoid using abbreviations or acronyms in the lede, as this can spoil the flow of the copy.

Generally don’t use a hyphen unless:
· The word that follows is capitalized, e.g. pre-Columbian
· You’re joining two prefixes, e.g. counter-counterargument
· The prefix ends with the same vowel that starts the word that follows, e.g. ultra-addictive. Exceptions to this rule abound, including double “e” words, e.g. preexisting, preempt.
Common prefixes:
· Co-
· Counter-
· Mega-
· Multi-
· Non-
· Pre-
· Semi-
· Socio-
· Super-
· Ultra-
Specifically for the prefix “co-,” use a hyphen for words related to a person’s occupation or position:
· co-author
· co-host
Use U.S. spelling for most situations. Beyond the obvious ones (colour vs. color), there are the subtler variations (fuelled/fuelling vs. fueled/fueling, or judgement vs. judgment). A good way to check is to search for it in the Merriam-Webster dictionary and go with the preferred spelling or first option used there.
However, don’t change the spelling of the name of an organization or agency if its proper name uses British English.
U.K. Labour Party
World Food Programme
Don’t change or correct spellings in quotes from U.K. to U.S. English. For misspellings, add [sic] after the word to denote the mistake was on the part of the speaker and not the writer.
Narrative can be in past or present tense, depending on the type of story. Present tense works well in feature writing or in “timeless” articles that can still stand on their own several months later. It helps keep the story feeling fresh. Conversely, past tense is more appropriate for a time-sensitive story like one reporting on a recently published study.
· A third-generation plantation worker, Juma says he sees little future for his own children on this rapidly drying land.
· The authors of the study called for further research to be done into the impact of increasingly severe storm surges on the mangroves.
Keep the tense consistent throughout a story.
