For example, people who took annual vacations in Ukraine stopped doing that suddenly about a year ago, and everybody knows why. Another example: After Mount St. Helens erupted a few years ago, fewer people wanted to climb dormant volcanoes in the Pacific Northwest. (I don't really know if that's true, but it makes a nifty example.)
An example of slower change is the way people respond to being told "Thank you." In my age group (the Older Than Dirt crowd), we were taught to say "You're welcome". Around the time my children became adults, people didn't say "You're welcome" any more, and everybody was saying "No problem." Now that even my grandchildren are adults, "No problem" has fallen by the wayside. Gen Z'ers and millennials say "Of course!"
The world continues to be a strange place, if I do say so myself.
B. Many words that start with S in English start with E in Spanish and French, I will now use my newly-acquired skill of creating a table with HTML to show you some examples.
C. Some alphabets have more letters than others. Here are some examples:
Hawaiian has 12 letters, 13 if you include apostrophe, and you probably should.
Greek has 24 letters. The one that looks like an X sounds like a K. The one that sounds like an X looks nothing like an X.
The Latin alphabet that we use for English has the 26 letters we know and love. J and W are fairly recent additions, relatively speaking. Old English had two letters called edh and thorn that have disappeared altogether.
The Russian alphabet has 33 letters. Several countries including Russia use the Cyrillic alphabet instead of the Latin one. When the old USSR used to send athletes to the Olympic Games, their uniforms said CCCP. Americans found this very confusing.
The Albanian alphabet has 36 letters, including ç, dh, ë, gj, ll, nj, rr, sh, th, and xh as distinct sounds. The xh sounds like a J. The J does not.
The Swedish alphabet has 29 letters consisting of the Latin letters A through Z plus Å, Ä, and Ö.
The written language of the Cherokee Indians is composed of 85 symbols that represent syllables (sounds) instead of letters.
Mandarin Chinese consists of around 50,000 ideographs although modern dictionaries contain only about 20,000 of them; an educated Chinese person might know about 8,000 of them. To be able to read a newspaper requires knowing between 2,000 and 3,000 of them.
All in all, I find the sort of stuff in this post to be very interesting. I hope you do too. I would hate to think I am talking to myself.
