### Biblical Occurrences & Contextual Analysis

### Theological Significance

* **Spiritual Barrenness:** The term vividly portrays the spiritual condition of false teachers. They exist within the community, participating in "feasts of charity" [[Jude 1:12]], yet they are like autumnal trees that produce nothing of value. They are **without fruit** `{{G175}}`.
* **Promise without Fulfillment:** Like clouds **without water** `{{G504}}` that are carried about by **winds** `{{G417}}`, these autumnal trees represent a failed promise. They have the appearance of teachers but offer no life-giving substance, only decay [[Jude 1:12]].

### Summary
In summary, `{{G5352}}` is a highly specific and potent word used once in Scripture to convey a powerful warning. While it literally means autumnal, its theological use in [[Jude 1:12]] paints a picture of false teachers who are spiritually dead, unproductive, and destined for judgment. It serves as a stark metaphor for a spiritual condition that is not merely lacking fruit, but is in an active state of withering and decay.
