in case - similar to "IF"?

Good day everyone,

In case you haven’t noticed
In case you didn’t noticed.
In case you hadn’t noticed.

Question 1:When do we use these? or in what situation/context?
Question 2: Do we use “in case” with subjunctive, like we use in “IF” statements?


Does this help?

Why start a new thread for the same question?

In case you haven’t noticed = in case you have not yet noticed.

In case you hadn’t noticed = in case you had not noticed up to the moment I started to draw your attention to it.

In case you didn’t notice = in case you did not notice it for yourself - this one is used in a different type of context to the two above: I am pointing this out in case you didn’t see it when you were left with the opportunity to spot it.

Thanks tofu.


The previous identical post had been left unanswered for some time, I was supposed to delete it before I re-post; however, the site wouldn’t allow me to do it. I had no choice but to create another one. I’m sorry for the multiple posts.

Back to the question and let me construct some sentences to make sure i got it right.

In case you hadn’t noticed: Yesterday, I left you a message again in case you had not noticed the previous one two weeks ago.

In case you didn’t noticed: In case you didn’t noticed the email i sent you yesterday, now, allow me to explain what’s in the email.

Please correct me if i got it wrong.

But, I still see some people have used “In case” followed by the present tense. This is something that has been confusing me.
For example:
“In case you hadn’t noticed, we are in an economic crisis here.”
Why not “In case you didn’t noticed” instead?
It’s found on this website:
incaseyouhadntnoticedwearein …

Sorry for the trouble. I appreciate your time.

If I phrase it like this, does it make more sense to you?
In case you had not noticed previously I am now pointing out to you that we are in an economic crisis.

It is personal choice whether to use that or to say,
“In case you haven’t noticed …”
In case you have not noticed up to this point I am now pointing out to you that we are in an economic crisis.

Both are acceptable forms with no significant difference in meaning. They can be used interchangeably.

You keep writing “In case you didn’t noticed” That is always incorrect.
‘In case you didn’t notice’, as I said earlier, is slightly different from the others because you are utilising a different verb entirely, not just a different tense.

Just to clarify, if we used “In case you HAD NOT NOTICED I am…”, is this phrase still consider the past perfect tense?
Because to me, we ONLY use the past perfect tense to compare TWO moments in the past.
Thanks for pointing out those “didn’t noticed”, as I think it must have been typos. :slight_smile:

By the way, is there any relevant topic that I can read up regarding this?
Thanks Beeesneees.

Hi Rickyrocky,

You are quite right about

and this is really what is happening here. The ‘earlier’ time is understood as follows: In case you hadn’t noticed refers to when this crisis started, which was before now.


Hi Alan,

If that is the case, what’s the second MOMENT that we are comparing?
If we aren’t comparing two moments? why do we use the past participle?

Thanks^ ^


In case you hadn’t noticed before the crisis started.


i see! Thanks. My light bulb has lit up.
