1. 'since'

You use since to say that something has been true from a particular time in the past until now.

Exam results have improved since 2001.
I've been wearing glasses since I was three.

Be Careful!
In sentences like these you use a perfect form with since. Don't say 'Exam results improved since 2001' or 'I am wearing glasses since I was three'.

You can also use since to say how long ago something happened. When you use since like this, use a simple form. For example, instead of saying 'I last saw him five years ago', you can say 'It's five years since I last saw him'.

It's three months since Kathy left.
It's years since I heard that song.
2. 'for'

If you want to say how long something has been true, use for, not 'since'.

We've been married for seven years.
I've known Adeel for ages.
See for
3. 'during' and 'over'

To say how long something has been happening, use during or over.

A lot of rain has fallen during the past two days.
Things have become worse over the past few months.
4. 'from ... to'

To say when something began and finished, use from and to.

Mr Ito was headmaster from 1998 to 2007.

Instead of 'to', you can use till or until.

The noise continued from nine in the morning till 5 p.m.

Be Careful!
Don't use 'since' and 'to'. Don't say, for example, 'He was headmaster since 1998 to 2007'.

5. used to mean 'because'

Since can also be used to mean 'because'.

Aircraft noise is a problem here since we're close to Heathrow Airport.

 When since is followed by a noun or noun phrase, you can usually translate it as desde:
Spain has changed a lot since Franco's death España ha cambiado mucho desde la muerte de Franco
 When since is followed by a verb phrase, use desde que instead:
Since I saw you a fortnight ago a lot of things have happened Desde que te vi hace quince días han pasado muchas cosas
! Use the present tense in Spanish to describe a situation that started in the past and has continued up to now (present perfect or present perfect continuous in English):
I have been here since this morning Estoy aquí or Llevo aquí desde esta mañana They've been waiting since nine o'clock Están esperando or Llevan esperando desde las nueve He has been taking more exercise since he talked to his doctor Hace más ejercicio desde que habló con el médico
NOTE But the perfect tense is used in Spanish when the verb is in the negative:
I haven't seen her since she left No la he visto desde que se fue
 Translate since then or ever since using desde entonces:
She came home at five and has been studying ever since Llegó a casa a las cinco y está estudiando desde entonces
 Translate long since using hace tiempo (+ que + ((PAST TENSE))) or hacía tiempo (+ que + ((PAST/PAST PERFECT))) as relevant:
His wife has long since died Hace tiempo que murió su mujer, Su mujer murió hace tiempo
Meaning "as", "because"
 In formal contexts you can usually translate since using ya que or puesto que. In more everyday Spanish, use como, which must go at the beginning of the sentence:
They could not afford the house since they were not earning enough No podían pagar la casa puesto que or ya que no ganaban bastante Since I hadn't heard from you, I decided to give you a call Como no sabía nada de ti, decidí llamarte
