IPA: /əˈprɒksɪmətɪv/
KK: /əˈprɒksɪmətɪv/
Relating to an estimate or something that is not exact but close to a certain value.
The approximative cost of the project was higher than expected.
Approximative is formed from "approximare" (meaning to come near) and the suffix "-ive" (meaning having the nature of). The word describes something that has the nature of being near or close to a certain value or condition.
Think of something that is 'coming near' ('approximare') to a certain value — that's why approximative means close to or nearly accurate.
