minimally invasive + {noun}

用法筆記

Often used with 'minimally' or 'less' to describe modern surgical techniques that reduce harm to the body. The opposite is 'non-invasive' (no cutting or insertion).

highly invasive + {noun}

用法筆記

Frequently used with cancer types ('invasive ductal carcinoma', 'invasive melanoma'). Distinguish from sense 1: here the focus is on internal spread within the body, not on medical procedures.

    synonym for non-native; less common in modern scientific writing

反義詞
  • native

    originally from and naturally found in the area

文法句型

invasive + {noun} (species, plant, animal, organism)

用法筆記

Common collocation: 'invasive species' (often shortened to 'invasive' as a noun — see noun sense). The key characteristic is that the organism is non-native AND causes harm, not just that it spreads.

常見錯誤

❌Dandelions are invasive in my garden.

💡'invasive' in this sense refers to ecological harm in a natural environment, not just weeds in a garden.

The most common everyday usage of 'invasive'. Often used to describe questions, searches, surveillance, or company data collection. Weaker than 'violating' but stronger than 'nosy'.

常見錯誤
