Sex used to be what you are (male or female), and an activity you partake in. Gender was a linguistic term noting (in those languages that made such distinction) whether a noun was male, female or neither..

Now sex is just the activity, while the linguistic term has been transferred to the physical being. BTW, I always cross out the word gender on applications, and replace it with the word sex. Someday where it asks sex I may answer either 'yes' or 'sometimes'.

Decimated, in classic times, meant to 'kill every tenth person'...prisoners of war, rebels, group punishment for disobeying orders, etc. Now it usually means wholesale slaughter regardless of the actual percentage killed, or severe cuts as in economic programs.

In my lifetime (not inconsiderable as lifetimes go, as I am beyond the Biblical three score and ten) sanctioned has always had the dual meaning, but sanctions (n.) has always meant punishmnet.

Likewise 'issue' has always had both meanings.

Gay, while always having the two meanings, now pretty much seems to be exclusively.

In these times of ferment, it is perhaps interesting to note that te word 'magazine' (from the Arabic) has meant a storage of armaments, and a booklet (storage) of written and pictorial articles.
