Fixed expressions and idioms: learn the situation too
Idiomatic language is useful only when you also know register, frequency and situation.
In short
Some expressions are partly predictable; others have meanings that cannot be reconstructed word-by-word. The safest learning unit includes the expression, a typical situation, who says it to whom, and a natural example.
How it works
Common fixed phrases such as お疲れさまです depend heavily on social context. A literal translation is less useful than knowing when it fits.
Useful contrast
Rare or literary idioms can wait. High-frequency conversational chunks provide more value early.
Examples
お疲れさまです。
A workplace acknowledgement such as “thanks for your work / good work.”
お先に失礼します。
Excuse me for leaving before you.
Common pitfall
Do not collect idioms just because they are colorful. Prioritize expressions you are likely to hear and can place correctly.
