Overview
- 1概要：いつは、時間的な問いかけを行う際に最も基本的な疑問詞です。英語の「When」に相当し、過去、現在、未来のいずれの時制に対しても使用可能です。2) 使用パターン：文の先頭、あるいは動詞の前に置かれることが一般的です。「いつ〜ですか？」という形が最も標準的ですが、文中に埋め込まれることもあります。3) 一般的な文脈：待ち合わせの時刻確認、イベントの開催日、過去の出来事の回想など、生活のあらゆる場面で登場します。4) 類似語との比較：「いつ」は単なる疑問詞ですが、「いつか」は不定の未来を指し、「いつでも」は条件を問わない全称的な意味を持ちます。また、より丁寧な表現として「いつ頃（いつごろ）」や「いつでしょうか」が使われます。

How to Use It
Notes d'usage
Use 'いつ' for direct questions about time. In formal settings, combine it with '頃' or honorific verbs to maintain politeness. It is a versatile adverb that fits almost any context involving temporal inquiry.
Erreurs courantes
Beginners often place 'いつ' at the end of the sentence like in English. Remember that in Japanese, it usually comes before the verb. Also, avoid using it when you mean 'sometime'; use 'いつか' instead.
Tips
Placement flexibility for natural flow
While 'いつ' usually starts a sentence, placing it before the verb makes the question sound slightly more focused on the action.
Avoid confusing with 'いつか'
Don't use 'いつか' when you need a specific answer. 'いつか' implies an indefinite time, which can frustrate someone expecting a clear date.
Politeness in time inquiries
In formal Japanese, adding '頃(goro)' makes the question softer. It shows consideration for the listener's schedule.
Origine du mot
Derived from ancient Japanese interrogative roots. It has been used since the Heian period to denote temporal inquiry.
Contexte culturel
Asking for time directly can sometimes be seen as demanding in Japan. Using 'いつ頃' (around when) is often preferred to show social grace.
Astuce mémo
Think of 'いつ' as the 'When' key. Just as you press a key to open a door, you use 'いつ' to open the door to time information.
