This question already has an answer here:

While writing programs, I need to create a drop down for setting periods, like daily, weekly, monthly, etc. Using one year as a time frame. This question is driven by lack of a better word. I've had some trouble coming up with a one word adjective for 6 months. I do have the following:

1 day - Daily,
1 week - Weekly,
1 month - Monthly,
3 months - Quarterly,
6 months - ?
1 year - Yearly or Annually

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Just being positioned between "Quarterly" and "Yearly" should mitigate the ambiguity. So either one would be understood. (It won't stop some from making a mental note that it might be the wrong word, but they will still know your intent.) I would go with semiannually, myself. Unfortunately, this question has been marked as a duplicate for which no authoritative reference was provided. So you'll have to be trusting, I guess. – Canis Lupus Mar 2 '13 at 21:29
The question started off as more-or-less clear, then veered off somewhere strange ("bi-annually is not one word"), and the update is just a wall of text with no question in sight. Anyway, we have several questions dealing with the ambiguity of bi- already. All of them boiling down to "1) yes, it can be ambiguous — big deal, so can be most words —, and 2) no, there is no convenient one-word replacement — again, big deal, neither is there for most things". Nothing wrong with clearly stating "every six months" or "twice a year". – RegDwigнt Mar 2 '13 at 21:36
Steward, I added an answer (to suggest considering twice-yearly and half-yearly) at english.stackexchange.com/a/105871/11433 which you can vote up if you feel like. – jwpat7 Mar 2 '13 at 21:37
@RegDwighт, in the “more-or-less clear” part, Steward asks, “Could there be a better word for it?” which isn't a duplicate of linked question. I added an answer at the other question. But please reopen this question and transfer my answer from the other question to this one. – jwpat7 Mar 2 '13 at 21:40
Thanks jwpat7, the fact is I'd vote up your answer. One word appearing in two different questions don't make it duplicates. While one question could be about what does bi- stand for, my question is what better one word is there for 6 months like daily, weekly, monthly, quarterly. My guess it there might be one that I don't know of. The link for duplicate don't address my issue, an answer would help. At the moment, I'd go with the one answer I have here. biannually. But there is half-yearly, bi-yearly won't be bad. – Steward Godwin Jornsen Mar 2 '13 at 21:59

Should do the trick, and fits with your running theme of -ly suffixes. It is spelt as one word.

Thanks, just concerned about this: data.grammarbook.com/blog/definitions/… and elearnenglishlanguage.com/difficulties/bisemi.html It says: Bi- comes from the Latin meaning two. When used with a temporal word, bi- means "every two" or "every other." Does that affect the meaning? – Steward Godwin Jornsen Mar 2 '13 at 21:11
Every two years is biennially. – Andrew Leach Mar 2 '13 at 21:21
I was actually looking for every 6 months. Thanks for the response Andrew. @mattacular, I'm thinking towards the same line if I don't get a better suggestion. – Steward Godwin Jornsen Mar 2 '13 at 21:23
@StewardGodwinJornsen I was pointing out that biannually is fine because the other word (for every two years) is biennial. I wasn't suggesting biennial for your requirement. – Andrew Leach Mar 2 '13 at 21:29
Okay, I get. That should mean two years then, not half of it. I wish I had a word like that for it. It's such an important time division to not have a word (latin, aramaic or something)! – Steward Godwin Jornsen Mar 2 '13 at 22:06
