The word "learnings" is a noun meaning "the knowledge or skill acquired through experience or study."
It's important to note that the word "learning" can be used as both a noun and a verb. When it's a noun, it's used to refer to the process of gaining knowledge or skill, while when it's a verb, it's used to describe the act of acquiring knowledge or skill.
Here are some examples:
* Noun: "Her learnings in the field of medicine are extensive."
* Verb: "She is learning a new language."
You would only use an apostrophe with "learning" if you were using it as a possessive pronoun. For example:
* "The student's learning was impressive." (Here, "student's" is possessive and indicates that the learning belongs to the student.)
