mensiversary 

MEN-SI-VER-SA-RY (mèn´se-vûr´se-rê) noun
1. The monthly recurring date of a past event, especially one of
historical, national, or personal importance: a first date
mensiversary; the mensiversary of the founding of Nerstone Pictures.
2. A celebration commemorating such a date.
from Latin: mensis, month + versus, past participle of vertere, to turn.

If the word for the commemoration of a yearly event is anniversary, by
analogy the logical word for the commemoration of a monthly event
should be "mensiversary." "Anniversary" comes from the Latin "annum,"
meaning year. (The "versary" part comes from a Latin word referring
to turning.) The Latin word for month is "mensis." Hence,
mensiversary. I've not found this word in any reputable dictionary,
but perhaps exposure in Google Answers can help to put it there.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
