Undershirt audio micro-course (transcript)
Podcast 1 — Introduction & meaning
Narrator: Today's word is "undershirt" — a noun, pronounced /ˈʌn.də.ʃɜːt/, with the stress on the first syllable.
Narrator: An undershirt is a light garment worn under a shirt, next to the skin, for warmth or comfort.
Narrator: In plain English, an undershirt is the thin vest or tee you wear beneath your outer shirt, usually hidden.
Narrator: It is the American term — in British English, this garment is most often called a "vest".
Narrator: The word is a simple compound — the prefix "under-", meaning beneath, joined plainly with "shirt".
Narrator: Its meaning has stayed wonderfully literal — a shirt worn under another shirt, nothing more.
Narrator: It serves quiet, practical roles — adding warmth, soaking up sweat, and protecting the outer layer.
Narrator: In tone it is everyday and practical, common in clothing, fashion, and daily routine.
Narrator: So remember: an undershirt is the hidden layer beneath your shirt — the British "vest", quiet and practical.

Podcast 2 — In conversation
Speaker A: It's freezing today — I've put an undershirt on under my jumper for extra warmth.
Speaker B: Sensible! Though over here we'd usually call that a vest, wouldn't we?
Speaker A: Exactly — "undershirt" is American, "vest" is British. Same hidden layer, though.
Speaker B: Right. A common confusion is that in America, a "vest" means a waistcoat!
Speaker A: Ha, true — so the words cross over completely. Easy to muddle up.
Speaker B: It really is. And an undershirt soaks up sweat, protects the outer shirt.
Speaker A: Good practical point. Close synonyms? "Vest", "tee", and "base layer".
Speaker B: Though "base layer" sounds sporty, for hiking and running and such.
Speaker A: Exactly. "Undershirt" keeps that plain, everyday feel.
Speaker B: And the spelling's lovely and logical — under plus shirt.
Speaker A: A humble word for a humble but handy little garment.
Podcast 3 — Prompt engineering
Speaker B: Let's use "undershirt" in AI prompts to mean a hidden base layer beneath what the user sees.
Speaker A: So undershirt in a prompt means an invisible underlying layer that supports the visible one?
Speaker B: Exactly. For app architecture, you'd write:
Prompt: Build my app with an undershirt layer beneath the UI — a service layer that handles all data and logic, so the visible components stay thin. Keep the undershirt hidden but doing the real work underneath.
Speaker B: The word "undershirt" makes it vivid — a quiet supporting layer under the surface.
Speaker A: Clear and memorable. What about styling?
Speaker B: Try this:
Prompt: Give my cards an undershirt of base styles — a shared foundation layer of spacing and colour under each variant. Keep the undershirt consistent so every card sits on the same hidden base.
Speaker A: So the base stays uniform underneath.
Speaker B: Right. For caching:
Prompt: Add an undershirt cache beneath my API — a hidden layer that serves stored results instantly and quietly refreshes underneath. Users never see the undershirt, but the app feels lightning fast.
Speaker A: What about a clothing app itself?
Speaker B: Here you go:
Prompt: Build a wardrobe app with layered outfits — let users stack an undershirt under a shirt under a jacket, and preview the layers. Track which undershirt pairs with which outfit.
Speaker A: Could undershirt shape a logging layer too?
Speaker B: Absolutely:
Prompt: Add an undershirt logging layer under every request — it quietly records timing and errors beneath the app without cluttering the code. Keep the undershirt invisible to users but always capturing.
Speaker A: So "undershirt" means a hidden supporting base layer.
Speaker B: Exactly — a homely word that tells the AI to build a quiet layer beneath the surface.
