also: ずくし
suffix
Attaches to nouns to mean 'every kind of that thing' or 'a full assortment of'. Common in set phrases like 国尽くし (all the countries) or 料理尽くし (a full range of dishes).
この店は日本全国の名産品尽くしです。

Kana spelling, often used when the kanji is not needed or for clarity.
Variant kanji spelling, less common but still used.
Irregular kana usage (ずくし instead of づくし); encountered occasionally but non-standard.
ずくめ also means 'entirely' or 'completely', but it emphasizes being covered or filled with something, often with a nuance of uniformity (e.g., 黒ずくめ 'all in black'). 尽くし focuses on variety and assortment.
Derived from the verb 尽くす (つくす, 'to exhaust, to use up'), with rendaku voicing to づくし. The suffix sense developed from the idea of exhausting all possibilities of something, hence 'all sorts of'.
