The phrase "locking in" has its etymology rooted in the verb "lock".
The word "lock" originally comes from the Old English word "loc", which was derived from the Proto-Germanic word "lukan". This ancient root word meant "to fasten" or "to close". Over time, the meaning of "lock" extended to include actions like securing or closing something firmly, often using a mechanical device or a key.
When the concept of "locking in" emerged, it retained the core idea of securely fastening or closing something. However, in the context of phrases like "locking in a decision" or "locking in an agreement", it implies making a commitment or firming up a decision. Just as a lock ensures security, "locking in" signifies making something fixed or certain.
