Our time is limited.

You're wasting our time.

Our son died in the war.

For a certain appointed time,

For a known calculated term.

till a known term decreed?

Till a limit known?

For a known period (determined by gestation)?

Just ignore him for a while.

For a known term?

until an appointed time?

So bear with him for a while.

until a known span of time ?

For a known extent.

Wait for some time. Perhaps he will come to his senses.

for an appointed time?

Till an appointed term,

for an appointed term?

For a period (of gestation), determined (according to need)?

He was waiting for a long time.

How long did you do it for?

We should spend our time creating content for our website rather than wasting time worrying about minor cosmetic details.

We had no unexpected incidents during our trip.

For a long time I wanted to meet him.

He has been sick for a long time.

I've been a teacher a long time.

Tom was silent for a long time.

I waited for Tom for a long time.

I've been silent for a long time.

And so this had me stymied for quite a long period of time.

Our English teacher is always on time.

Uncertainty reigned for a considerable time.

How long have you been teaching English?

How long can you hold your breath?

How long have you been learning English?

How long have you been looking for it?

How long has he lived in London?

She always has time in the afternoon.

And in that time, I have seen a lot of changes.

Nature has been doing that for a long time.

Asia has been neglected for far too long.

This is clearly no longer the case today.

And so we spent a good deal of our time indicating that.

Our teacher is at once stern and kindly.

Your brother spent a lot of time with our teacher yesterday.
