   • Luxuriant, dense, lush: Describes vegetation, plants, or hair that grows thickly, abundantly, and in a disorderly, intertwined manner, creating a dense mass.

Variants and Related Words

• Um (verb): To buzz, hum, or murmur (as of a crowd). While "um" alone is different, it contributes to the auditory imagery of dense growth in "um tùm".
• Rậm rạp (adj): Dense, thick (vegetation). A close synonym, but "um tùm" often implies a more chaotic, overflowing lushness.
• Sum suê (adj): Luxuriant, full (of foliage). Focuses more on healthy abundance than chaotic density.

Synonyms

• Luxuriant: Growing thickly and healthily.
• Dense: Having parts closely packed together.
• Thick: With many parts in a small area.
• Bushy: Thick and spreading like a bush.
• Rank: Growing too thickly and coarsely.
