覚え方のコツ Memory Tip
annual は「年ごとの」で、bi- は bicycle や bilingual と同じく「2」の感覚を持つ接頭辞です。biannual は「1年を2つに分ける」と考えると、予定が6か月ごとに来るイメージになります。semiannual もほぼ同じ意味で、こちらは semi-「半分」が見えるためより誤解が少ない語です。別エントリの「年2回の」は回数に注目し、この語義では間隔の規則性に注目します。
Think of annual as "yearly" and bi- as the same prefix in bicycle or bilingual, which gives the idea of "two." If you split one year into two parts, something biannual happens every six months. The word semiannual is very close in meaning and is often clearer because semi- directly suggests "half."

覚え方のコツ Memory Tip
biannual は「1年の中で2回ある」という回数に注目して覚えます。bi- は bicycle, bilingual と同じ「2」、annual は「年ごとの」なので、「年単位で数えると2回」と組み立てられます。biannual meeting, biannual report, biannual checkup のように、会議・刊行・検査などが年に二度実施される場面でよく使います。biennial は「2年に1回」なので混同に注意します。
Start from annual, which means something that happens every year. Add bi-, the same two idea you see in bicycle or bilingual, and you get twice in one year. It is often used with meetings, reports, and checkups. Be careful not to mix it up with biennial, which means once every two years.

biannual の語源・成り立ち Etymology
biannual は bi-「2つ・2回」と annual「年ごとの」から成ります。annual はラテン語 annus「年」に由来し、「1年を2回に分ける」感覚から半年ごとの意味になります。
Biannual is made from the prefix bi-, meaning "two" or "twice," and annual, meaning "yearly." Annual comes from the Latin word annus, meaning "year," so biannual developed the sense of dividing the year into two parts, or happening every six months.
