I was in an Argos shop the other day and saw their nice thick catalogue.
A shop is a place where old people can buy things to take home instead of being delivered or 3D printed.
A "catalogue" is like Amazon, but printed on paper. It is a "book" with "pages" showing things to buy, like web pages.
"Paper" is a display system made from poor innocent trees. It has a digital interface if you lick your finger and then use it to turn the pages.
"Licking" is a form of intimate greeting that we used before SARS bird flu swine flu coronavirus golgotha plague.
