We take fonts for granted these days, its good to pause and look back at some typography history to see how and why things were made. When I work on design for a project, I take into consideration the form of fonts as well as the functionality.
Serif is a french word and, you can open the link to the google translation and hear the way it is said in french.

Many years ago before computers letters were carved on wood using a chisel. The tools would not blunt and not so accurate so when they carved out the letters a little would be left at the end. The printing press was used to make print books and newspapers. If you are interested in reading up about it follow this link.
Google defines a serif as : a slight projection finishing off a stroke of a letter in certain typefaces.
On paper it's easier to read serif fonts, because the serifs help the letters blend together and it is physically easier on the eyes and brain.
Wikipedia defines it as:
In typography, a serif (/ˈsɛrɪf/) is a small line attached to the end of a stroke in a letter or symbol. A typeface with serifs is called a serif typeface (or serifed typeface). A typeface without serifs is called sans-serif or sans serif, from the French sans, meaning "without". to read the rest of the article go here https://en.wikipedia.org/wiki/Serif.
Once modern equipment and tools became available the fonts started improve as they were able to get rid of the serif. The reason we think of serif fonts as old is because all the old scripts and books were with a serif, all modern fonts had the serif removed.
I like to use Sans-Serif fonts for my designs as they look more modern, let me know which ones are your favorite fonts.
Today there are tools for every kind of design item you want to make. When I first started in design way back in 2003 we have a few software tools that we would use to do almost everything.
Those where Photoshop, Adobe Illustrator, Flash. With those tools we could do website designs, animations, character illustrations and many other things.
Now if you take 1 application like Adobe XD you see there are another 10-15 apps that do the same but with their own advantages. It makes it hard to choose the tools you need any more. But if I can give you 1 advice that my university professors told me it was: Photoshop is just a tool just like a pencil, those will not make you creative it will just make your task faster and easier.
I like to say that whatever tools there are we can learn it easy. Remember to use your mind and practice your creative techniques such as drawing with pencil. For software, use whatever software you feel comfortable with that gets you results.
