Podcast 1 — Introduction & meaning

Narrator: Today's word is "past" — noun, pronounced /pɑːst/, with the stress on "past", the single syllable.

Narrator: The past is the time that has already happened, together with the events and experiences belonging to it.

Narrator: In plain English, it is everything that came before now, from a second ago to a thousand years ago.

Narrator: It comes from the old participle of the verb to pass, so the past is simply the time that has passed by.

Narrator: A common collocation is "in the past", which describes something that used to be true but is no longer the case.

Narrator: It differs from history, because history is the studied, recorded account of events, while the past is the raw stretch of time itself.

Narrator: Figuratively, we speak of a person with a past, meaning someone whose earlier life holds secrets or scandal; and as an adjective and preposition it means former, or beyond, as in past president, or half past three.

Narrator: Historians, lawyers, therapists, archivists and software engineers all rely on it, especially when handling past records, past versions and past dates.

Narrator: So remember: the past is time already gone, and everything that happened inside it.

Podcast 2 — In conversation

Speaker A: Why does such a short word carry so much weight in English?

Speaker B: Because PAST is everywhere! It grew out of the old participle of pass, so it literally means the time that has walked by, and it works as noun, adjective, preposition and adverb.

Speaker A: So one spelling really does all four jobs?

Speaker B: Absolutely, it does. In the past is a noun, past experience is an adjective, past the bank is a preposition, and he walked past is an adverb.

Speaker A: Example sentences?

Speaker B: "We have made mistakes in the past." That means earlier in time. "Her past performance was excellent." That means previous. "The train went straight past the platform." That means beyond, without stopping.

Speaker A: Common mistakes?

Speaker B: Do not confuse past with passed: passed is the verb form, as in she passed the exam, while past is never a verb. And say half past three, not half passed three.

Speaker A: Close relatives?

Speaker B: Former is the tidy cousin, previous is the near twin, and bygone is the poetic alternative; yet plain old past keeps its simple, timeless charm!

Podcast 3 — Prompt engineering

Speaker B: Let's use "past" in AI prompts — useful for filtering historical records in a database and for writing release notes about previous versions.

Speaker A: How would that apply to a reporting dashboard?

Speaker B: Ask the model to summarise a fixed window of time.

Prompt: Summarise our support ticket volumes for the past ninety days and highlight the three largest changes compared with the previous quarter.

Speaker A: And for database work?

Speaker B: Have it generate a query that isolates older rows.

Prompt: Write an SQL query that selects all orders with a created date in the past twelve months and flags any customer whose past orders were all cancelled.

Speaker A: What about documentation?

Speaker B: Make the model contrast the current release with earlier ones.

Prompt: Draft release notes that explain what changed since the past three versions of the application, using clear past tense throughout.

Speaker A: One more?

Speaker B: Yes, let's use it for validation logic in a booking form.

Prompt: Write a JavaScript validation function that rejects any appointment date set in the past and returns a friendly error message to the user.
