同義詞
  • unmapped

    very close in meaning; uncharted is slightly more literary and implies a lack of exploration too

  • unexplored

    focuses on the place not having been visited, whereas uncharted emphasises the absence of a map

  • unknown

    broader — can describe anything not known; uncharted is specific to places

反義詞
  • charted

    direct opposite — recorded on a map

  • mapped

    equally direct; mapped is more common in everyday speech

文法句型

uncharted + noun (attributive)

be + uncharted (predicative)

remain + uncharted (predicative after linking verb)

用法筆記

Appears mainly in geography, exploration, and cartography writing. The word implies both that no map exists AND that the place has not been systematically visited. Compare with unmapped, which only says there is no map.

✅The restaurant was not marked on Google Maps.

釋義

史無前例

全新、無前例可循的狀況或領域

describes a situation, subject, or experience that no one has dealt with before, so it feels uncertain and hard to navigate — for example, a new area of research or a personal challenge without any clear path forward.

例句

Hana 在十九歲成為母親時，覺得自己踏入了史無前例的領域。

同義詞
  • unfamiliar

    weaker — unfamiliar simply means the speaker does not know it; uncharted implies nobody has mapped or dealt with it before

  • novel

    formal synonym that stresses newness without the feeling of risk that uncharted carries

  • unprecedented

    means nothing like it has happened before; uncharted adds the flavour of being lost or without guidance

反義詞
  • familiar

    well-known and understood; the opposite of new and uncertain

  • routine

    done many times before, posing no uncertainty

文法句型

uncharted + abstract noun (territory, waters, ground)

be + uncharted

enter + uncharted + noun

venture into + uncharted + noun

用法筆記

Almost always used with the nouns territory, waters, or ground. Unlike sense 1 (NOT ON A MAP), this sense is entirely metaphorical — it does not describe physical places. Distinguish from sense 1 by checking whether the subject is a real location (sense 1) or an abstract situation (sense 2).

常見錯誤

❌The hikers walked into uncharted territory deep in the forest.' (talking about literal geography → use sense 1).
✅The research team entered uncharted territory with their new gene-editing technique.
💡abstract or metaphorical fields call for sense 2.
