AA的Ngrammar point · tier 2 · stative-verb reduplication as attributive (a vivid AA的 noun)
Doubles a one-syllable quality word and pins it with 的 onto a noun, painting the quality as a lived, dwelt-on image.
字源 FORM what the parts do
The quality word is said twice, AA, and 的 ties it to the noun behind. The linker 的 borrowed the whole graph and wore its sound to a breath; here it does the same pinning job as in 我的、紅的. The doubling carries the coloring; 的 carries none of it.
故事 STORY a scene to remember it by
One stroke of paint names the color; a second stroke laid over it makes the color glow.

[stative verb AA] 的 [noun]
觸 · Trigger
You want the noun to carry a felt, savored quality, not a flat label.
序 · The move
1Take the one-syllable quality word and say it twice: 短 → 短短.Is it a stative verb (a quality), not an action verb? Only quality words double this way.
2Attach 的, then the noun: 短短的時間.No degree adverb in front — the doubling already supplies the warmth, so 很短短的 is wrong.
3Read it back as a painted image, not a measurement.Does the doubled form feel vivid and lingered-on? If you only mean a neutral fact, use the single 短的.
例 · Examples
1這間店的蛋糕很有名，總在短短的a short, short — a vividly brief時間stretch of time內within就賣完了。
This shop's cake is famous; it always sells out within a very short stretch of time.
界 · Boundary
單音狀態動詞做定語 (single Ade N, e.g. 短的時間)
Single 短的 states the quality flatly; doubled 短短的 colors it — savored, vivid, lingered-on. The separating feature is feeling, not degree: the doubling adds warmth, never a stronger amount.
很短的 grades the quality with an adverb out front; 短短的 carries the warmth through the doubling and refuses the adverb (✗很短短的). Adverb means more; doubling means felt.
✗ 很短短的時間 → ✓ 短短的時間 (the doubling already does the work; no degree adverb in front)
✗ 跑跑的人 → ✓ 跑步的人 (action verbs don't reduplicate as attributives; only quality words do)
✗ 短短時間 → ✓ 短短的時間 (keep 的 to pin the doubled quality onto the noun)
English has no doubling device; speakers reach for an adverb ('a very short time') and write 很短的, missing the lived, painted coloring that 短短的 gives.
