釋義

A borrowed Greek element meaning 'in two' or 'apart,' attached to nouns and adjectives to form words that describe division, separation, or duality — for example, dichotomy (a split into two opposing groups) and dichromatic (having two distinct colors).

例句

The dichotomy between rich and poor continues to widen across the country.

dichotomy = noun meaning division into two

The peacock's dichromatic feathers shimmer in green and gold under sunlight.

dichromatic = adjective meaning two-colored

同義詞
  • bi-

    Latin prefix meaning 'two'; used in everyday words (bicycle, bilingual) while dich- appears in formal/scientific vocabulary

  • di-

    Greek prefix meaning 'two' or 'double'; found in words like dioxide, diphthong — overlaps in meaning but not interchangeable (dich- adds the sense of separation/division, not just duality)

用法筆記

The form attaches to Greek-derived bases ( -dichotomy , -dichromatic ). It does not combine freely with native English words — you cannot form invented compounds like *dich-house* or *dich-group*. Common in academic, scientific, and technical writing.

❌The two paintings show a dichotomy in style.' (when the speaker simply means 'difference').
✅The two paintings show a contrast in style.
💡'dichotomy' means a division into two opposing groups, not just any difference.
