Sure skills are things that your character can do. Some examples of these are
Unarmed Combat
Running,
Sewing
Singing
Basically if it an activity that your character can do then its considered a skill. Points are awarded in theses as your characters practice them in IC posts. Graders, Story Tellers grade your completed threads.
Here Is the master Skill List. However not all skills are necessarily listed here but a good majority of common ones are.
Lores are bits of information that your character can learn that can't be expanded on. Like "Roses need sunlight to thrive" <--- this will never change, you won't be able to gain any more knowledge on the topic that Roses need Sunlight. That is a Lore, and these are accumulated in IC encounters to show the information and knowledge your character has accumulated
