IPA: /ˌpriːkəˈmɪt/
KK: /priˈkəmɪt/
A decision made in advance to commit to a certain action or choice.
The team made a precommitment to finish the project by the end of the month.
Precommitment → It is formed from "pre-" (meaning before) and "commitment" (from Latin "committere", meaning to entrust or to commit). The word refers to the act of committing to something before it happens or making a decision in advance.
Think of making a decision 'before' ('pre-') you actually commit to it — that's what precommitment means.
