意味
Thoroughly, completely, in every detail.
文化的背景
The phrase is deeply linked to the 'Ménage de printemps' (Spring Cleaning), a cultural ritual where families clean their homes thoroughly after winter. Politicians often use this phrase to promise radical, systemic changes to laws or institutions, appealing to the desire for 'rigueur'. Classic 19th-century novelists used this level of detail to describe social structures, implying that to understand a character, you must know their environment 'de fond en comble'. In Quebec, while the phrase is used, you might also hear 'de bord en bord', though 'de fond en comble' remains the more formal and standard choice for thoroughness.
Use with 'Fouiller'
If you want to sound like a native detective or someone who lost their keys, pair this with 'fouiller'. It's the most natural combination.
Don't pluralize
It is always 'fond' (singular) and 'comble' (singular). Even if you are cleaning multiple houses, the idiom stays singular.
