Serving to amplify or enlarge; having the function or effect of making something greater or more noticeable.
From amplify + -atory suffix. The -atory suffix (Latin -atorius) means 'relating to' or 'serving to do,' creating adjectives that describe purpose or function.
English speakers often choose between -ative and -atory for the same root word—compare 'talkative' vs 'oratory.' Both work, but they often have subtle differences in how formal or specific they sound.
