Where does “preteen” come from?

I need to work through this chain carefully, but I notice there's a problem: the chain provided doesn't actually connect "preteen" to its components logically. The chain shows "prae-" (Latin prefix meaning "before") but then traces "dū-" and related words that don't support "preteen." However, I'll apply the rules to what's given: The chain as listed goes: English teen ← Middle English tenen ← Latin prae- ← Latin prae ← PIE dū- ← Gaulish dunum ← Proto-Celtic dūnom ← PIE dʰewh₂- But this is incoherent—"prae" doesn't derive from "dū-" in the way shown. Given the impossibility of creating an accurate sentence from this chain without inventing steps, I should note: **I cannot write an accurate origin sentence from
