Sky Words Level 4378 - Complete Answer Guide
Welcome to the complete answer guide for Sky Words Level 4378, part of the Extended world (levels 4,378–4,378). This level presents you with 4 letter tiles — BERT — and asks you to form all 6 valid words ranging from 3 to 5 letters. Every word on this page has been confirmed from live game data so you will never get a wrong answer here.
The key to beating Level 4378 is placement order. Place BERET first — at 5 letters it is the longest word and reveals the most crossing tiles for the shorter entries. Once you have the longest word locked in, each crossing tile you reveal narrows down the remaining slots and the shorter words fall into place almost automatically. If you are completely stuck, scroll down to the Word-by-Word Breakdown — each entry gets its own vowel/consonant analysis so you can target the exact word that is blocking you. You can also jump straight to Level 4379 or browse the Extended world overview for the full picture of this world’s levels.

Winning Strategy for Level 4378
Level 4378 is part of the Extended world (levels 4,378–4,378). Place BERET first — at 5 letters it is the longest word and reveals the most crossing tiles for the shorter entries. Once the longest word is locked in, the shared letter at each crossing point gives you 1–2 confirmed tiles in shorter entries — which usually makes them instant fills.
Available letter set: BERT. Letters can be reused across different words in the same level.

Every tile in BERT is reusable
All 6 words are built from just 4 tiles — BERT — and each letter can appear in as many words as needed. No single-use restrictions. If a word seems impossible, you are not missing tiles — check the crossing positions instead.
