Usage Notes
When using 「決定」, it often implies a conclusive and official choice rather than a casual preference. For example, saying "進学先を決定する" suggests a serious and final choice about which school to attend.
A common learner mistake is confusing 「決定」 with 「決める」, which is the verb "to decide." Remember that 「決定」 is a noun and often used with the verb 「する」 to form "to decide." For example, "会議で決定した" means "decided at the meeting."
Register
「決定」 is neutral to formal and is appropriate in business, academic, and official contexts. In casual speech, people might use 「決める」 more often.
