What Happened? What Was Happening? Past Simple vs Past Continuous

What Happened? What Was Happening?

Past Simple vs Past Continuous — starring Philo, Sophia, and (once again) a broken bench.

The Big Idea

Some things in the past are finished, complete events — they started and ended. Other things were already in progress at a certain past moment — going on, not finished, when something else happened. English uses two different verb forms for these two ideas.

Philo
PhiloYesterday, Marcos knocked over the shelf. Finished. Done. That's the past simple — a complete action.
Sophia
SophiaBut something else was already happening when it fell — I was writing a letter. Past continuous: an action in progress at that past moment.
Sophia
SophiaPut them together, and you get the classic sentence: I was writing a letter when Marcos knocked over the shelf.
Marcos
MarcosI wasn't knocking anything over. I was testing its balance. There's a difference.
Philo
PhiloWhile Sophia was writing, I was reading. Two things in progress at the same past time.
Marcos
MarcosAnd I walked away. Very quickly. That part happened fast, start to finish — past simple.

So remember

Past simple = the whole action, start to finish, like a dot. Past continuous = the middle of an action, still going on, like a stretch of time — often interrupted by a past simple action.

The Two Forms

Past Simple

(verb) + -ed, or irregular Past Present Future
Marcos knocked over the shelf yesterday.

A complete action, finished, with a clear start and end.

Past Continuous

(was / were) + verb-ing Past Present Future
Sophia was writing a letter when Marcos knocked over the shelf.

An action already going on — interrupted by something shorter (the X).

Spelling: Regular Past Simple (-ed)

RuleExamples
Most verbs: add -edwalk → walked, jump → jumped
Ends in silent -e: just add -dlike → liked, dance → danced
Consonant + y: change y → iedstudy → studied, carry → carried
Vowel + y: just add -edplay → played, enjoy → enjoyed
Short word (one vowel + one consonant): double the last letterstop → stopped, plan → planned

Irregular verbs — no rule, just memory!

Spelling: Past Continuous (-ing)

Past continuous always uses was / were + a verb ending in -ing — the same -ing rules as always.

RuleExamples
Most verbs: add -ingread → reading, walk → walking
Ends in silent -e: drop the e, add -ingwrite → writing, make → making
Short word: double the last letterrun → running, sit → sitting
SubjectForm
I / he / she / itwas + verb-ing
you / we / theywere + verb-ing

Marcos's Favourite Trick, Even Back Then: "was always" + -ing

Just like in the present, "always" with the past continuous isn't a calm fact — it's a complaint about something that kept happening, again and again, and annoyed someone.

Neutral factAnnoyed complaint
Marcos always lost his stylus last year.Marcos was always losing his stylus!
Marcos always broke things as a boy.Marcos was always breaking things!
SophiaEven as a child, you were ALWAYS losing that stylus!
MarcosI prefer to say it was always finding new places to be.

Three Kinds of Sentence

Past simple uses did to help; past continuous uses was/were.

Past SimplePast Continuous
PositiveMarcos knocked over the shelf.Sophia was writing a letter.
NegativeMarcos didn't knock over the shelf.Sophia wasn't writing a letter.
QuestionDid Marcos knock over the shelf?Was Sophia writing a letter?

Notice: the -ed ending only appears in the positive statement. "Did Marcos knock…?" — not "Did Marcos knocked…?" The did already carries the past.
