The word "proficiency"
Here, with easy words, I try to tell you the word "proficiency" used in the previous article.
For the word, the following is noted in the OALD;
"the ability to do something well because of training and practice."
I would tell you, "I mean the word as
the skill level of getting better for the goal of a master skill."
That is my current proficiency for understanding the word. Even if wrong for real meaning, the meaning is what I hoped to tell you.
