• sketchy 本词

  Refers to a rough, vague account lacking detail, often sounding unreliable or hastily made; informal, typically describing plans, notes, or directions.

Partial and sketchy both describe something incomplete, but differently. Partial means covering only part of a whole amount, without suggesting the details are vague or unreliable, as with a payment or answer. Sketchy means rough and lacking detail, sounding unreliable, typically describing plans or directions.

这两个词都可以表示“不完整”，但侧重点不同：partial 强调只是整体中的一部分，不涉及信息是否含糊或可靠；sketchy 强调内容粗略、细节不足，语气较随意，常暗示不太可靠。这里不比较 partial 表示“偏袒的”的义项，也不比较 sketchy 口语中表示“靠不住的、可疑的”的义项。
