いわゆる

• Reading: いわゆる
• Romaji: iwayuru
• Formation: いわゆる + Noun

Meaning

A noun modifier meaning 'what is generally called' or 'so-called,' used to introduce a term that is widely known or commonly used, sometimes with a nuance of distance or quotation.

いわゆる precedes a noun to signal that the following term is a commonly used label, category, or expression. It can be neutral, simply introducing a well-known term (いわゆるグローバル化 — what is known as globalization), or it can carry a distancing nuance, suggesting the speaker does not fully endorse the label (いわゆる専門家 — so-called experts). It is similar to English quotation marks around a term. Unlike という, which reports what someone said, いわゆる indicates general public usage of a term. It appears frequently in academic writing, journalism, and explanatory speech. It always directly precedes a noun without particles and cannot be used predicatively.

Examples

1. いわゆるワークライフバランスの実現は容易ではない。 Achieving what is called work-life balance is not easy.
2. 彼はいわゆる天才肌のタイプではなく、努力の人だ。 He is not the so-called genius type, but rather a person of effort.
3. この地域はいわゆる過疎地域に分類されている。 This area is classified as a so-called depopulated region.
