The word font was not originally synonymous with the word typeface. The font was a set of metal letters used to print words. Two different sizes of the same typeface were different fonts.
The word logo was short for logotype. A symbol such as the Texaco star was a trademark, not a logo. But the two words are now used interchangeably.
Unlike Latin, English is a living language and meanings change over time. People need to get over this decimate thing!
I’ve heard that “logo” was supposed to be an abbreviated form of “logogram” too. But ultimately, it comes from the Greek word “logos”, which means “word” (and that’s the word translated as “the Word” in reference to Jesus Christ).
You decimate our language.
And we should all pause for a moment to morn the passing of the use of the possessive case as the object of a gerund. ..... My having said that, now back to using adjectives as adverbs.
