beta Grove is new and still finding its feet. Too hard? Too easy? Did it reject a fair answer? Tell us.
Families of words, hidden in plain sight
You don't need to know Latin to know Latin. Avenue, souvenir and prevent look like they have nothing in common — but they all come from venīre, "to come". An avenue is the way you come to a place; a souvenir is something that comes back to mind; to prevent is to come before. Grove hides a few families like that in one board of everyday words and asks you to sort them out, then say what each family's root means.
The roots change their spelling from word to word, and the boards are built to mislead: invent, inspect, insert and include all start with in- but come from four different roots (come, look, join, shut). Look past the prefix to the piece that carries the meaning.
Naming the root is the second half. Any word for the idea counts — come, arrive and approach would all do for venīre — and a guess that misses is ranked by how close it is in meaning, so you can steer toward the answer. When a family is named, every word is spelled out literally: a companion is someone you share bread with; a muscle is a "little mouse".
