A Tradescantia, I believe.

Something like this :

thanks Carol and Floral! Very excited to know what it is after three years lol

I'd love a closeup if possible pls of what you call the tendrils w/ nodules. I've never seen this plant before, but it's recognizably part of the plant family commonly known as Wandering Jews (Tradescantia). Yours is a very nice plant, looks well cared for, it's so nicely compact. Do you pinch it back from time to time & put the pieces back in the pot? That's one way to keep it so nice & full looking.

Karen thanks for the kind words! It was very scraggly before and I am still very much a beginner and know less about houseplants than I do about outdoor ones haha. It bad looked pretty awful so I cut/pulled off all the gross looking strands (not sure what to call them exactly), and really cut back the length of the remaining healthy ones. It also occurred to me I had nearly never fertilized any of the houseplants, so I gave them all a nice liquid fertilizer, and also started using filtered water instead of tap. Our tap water is NASTY and reels of chlorine so I assume it negatively imlavtedtje plants because they are all doing better now (in addition to the fertilizer).

Perhaps nodules isn't the correct term but this is what iamtalking about - there are whitish lumps/striations in the strands

The parts with leaves attached that grow longer are called runners, lianas, or sometimes just 'vines'. A tendril is a specialized shoot the plant uses to secure itself to something that offers support and opportunity for the runners can gain ht. What you referred to as nodules are nodes. Nodes are specialized structures that contain a special type of cell that can differentiate into either roots or shoots. When you prune a runner, new branches emerge from the crotch formed by the leaf and a runner, or from a point just distal to the scar where a leaf was formerly attached to the runner. Pinching/pruning the plant increases branching.

In the case of Tradescantia you could simply call them trailing or lax stems since they don't have any climbing mechanism. I would not call them lianas or vines which both imply climbing.
