a few hours before v.s. a few hours ago

[Lost_Soul]

Hi,

Can I say I did it a few hours before ? (I want to say that I did it a few hours ago)

Thanks !

Hi Alex

Generally speaking, you can only replace 'ago' with the word 'before' in reported speech or in a text in which 'before when' is clear. Usually the tense of the verb will be past perfect:

Direct speech: I did it a few hours ago.
Reported speech: He said he had done it a few hours before.

Having gone to bed only three hours before, he didn't hear the alarm when it went off at 5 a.m.
==> Having gone to bed = (Because he) had gone to bed
==> three hours before = three hours before 5 a.m.

Hi, Amy
Many thanks !

Actually, I just remembered that rule about turning "direct speech" into "indirect speech". This rule states that we must perform the following changes:

Ago -> Before or earlier.
Next week / month / year -> the next week / month / year OR the week / month / year after OR the following week / month / year.
tomorrow -> the day after / the next day / the following day
now -> then
today -> that day
tonight -> that night
yesterday -> the day before / the previous day
Last week / month / year -> the week / month / year. before OR the previous week / month / year.

Hi Yankee,

What about, "I did it a few hours back"?

Does it sound OK in direct speech?

Hi Daemon

So sorry to answer so belatedly.

Your sentence sounds unnatural to me. The word 'back' is occasionally used (instead of the word 'ago') to talk about a time in the past. However, I'd say the time referred to would usually be more distant than 'a few hours ago':

- a few months back
- a few years back
