straggly
Messy and uneven, with parts sticking out everywhere.
Straggly describes something that grows or spreads in an untidy, irregular way, with parts sticking out in different directions. A straggly plant might have stems sprawling messily instead of growing in a neat shape. Straggly hair hangs in uneven, wispy strands rather than falling smoothly. A straggly beard grows in patches, with some hairs longer than others.
The word often describes plants that haven't been trimmed or cared for: a straggly hedge might have branches poking out at odd angles, or a straggly vine might climb up a fence in a tangled, disorganized way. You might see straggly weeds pushing up through cracks in a sidewalk.
The word can also describe a group of people or things scattered and spread out rather than together. Imagine hikers on a trail: at the start they walk in a tight group, but after a few miles they might form a straggly line, with some far ahead and others lagging behind. The word captures that sense of things that should be together or organized but instead are messy, scattered, or growing every which way.
