Biannual vs. Biennial

Today’s Tip of the Day was sent in by Gilbert Ruegg, a loyal member of the Peanut Gallery and official FOJ (Friend of Jeanne).

Biannual: means occurring twice a year

Biennial: means occurring every two years or lasting for two years

Because these can easily be confused with each other, I prefer to use “semiannual” (Note: there is no hyphen) rather than biannual, which means occurring every six months, which works out to twice a year. However, if the event happens twice a year but not six months apart, biannual would be preferred.

“Back to School” happens in August and January every year here in Texas, i.e., twice a year, but not strictly semiannually, which would be July and January. And we are darn glad we don’t have to go to school in the “dog days” of July!

Here’s another example Mom sent me of how human brains work to help unravel something that a computer would see as gibberish.

Can you raed this? Olny 55 people out of 100 can.
I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg.
The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at
Cmabrigde Uinervtisy, it dseno’t mtaetr in what oerdr the ltteres in a word
are, the olny iproamtnt tihng is that the frsit and last ltteer be in the rghit
pclae. The rset can be a taotl mses and you can still raed it whotuit a
pboerlm. This is bcuseaethe huamn mnid deos not raed ervey lteter by istlef,
but the word as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling
was ipmorantt!
